Best for
Heart Of The Cosmos is a hillside house in Kosmos arranged as three self-contained rooms with an unusually well-equipped wellness area attached. Between them the rooms take six adults, each has its own kitchenette, and the shared spaces include a swimming pool, a hot tub, a sauna and a plunge pool. It suits couples who want a long, slow weekend without leaving the property much; two or three couples travelling together who like the idea of independent units around a communal terrace; and anyone whose ideal Saturday involves a sauna and a book rather than an itinerary.
Several policies narrow the field deliberately. The minimum age at check-in is 18, pets are not accepted, and bachelor and bachelorette parties are declined. Access is by stairs only and the property is not wheelchair accessible, which is a genuine exclusion rather than a caveat.
Location and setting
Kosmos climbs the slope on the western side of the Hartbeespoort basin, and the property sits up in that terrain with the water below it and the Magaliesberg ridge behind. The rooms look out over the lake and the mountains, and each has a balcony to look from. It is a residential hillside, so the immediate surroundings are gardens and neighbouring houses rather than shops or a promenade.
For the wider picture: the whole valley falls inside a designated biosphere reserve of some 357,870 hectares, nominated for UNESCO listing in 2015, and the bird list compiled across that area reaches 443 species. From a balcony above the water, that mostly translates into fish eagles, hadedas and a considerable amount of noise at first light, which is either a feature or a warning depending on your sleeping habits.
Rooms and accommodation style
The house has three bedrooms and four bathrooms, sleeping six in total. The distinguishing feature is that each room functions as an independent unit rather than a hotel bedroom.
- Every room has its own kitchenette with a microwave, a toaster, an electric kettle, a refrigerator and kitchenware.
- Each has a sitting area and a balcony, with lake or mountain views.
- Air conditioning, a flat-screen television with streaming services, and free Wi-Fi come as standard.
- Bed linen and towels are supplied.
The practical effect is that you can make your own coffee, keep your own milk and eat breakfast on your own balcony without negotiating a shared kitchen — the part of small guest-house living that most often goes wrong. It is not a full kitchen, though, and that distinction matters when you plan meals.
Facilities and on-site experience
The wellness cluster is the reason most people book. A swimming pool is available year-round, and alongside it sit a hot tub, a sauna and a plunge pool in the communal area. Those facilities keep set hours, opening at 08:00 and closing at 18:00, and anyone under 18 must be supervised by an adult at the pool, the sauna and the jacuzzi.
Outside, there is a patio, a terrace, a garden, an outdoor dining area and barbecue facilities, which between them cover most of what a self-contained stay needs. Free private parking is provided on site. There is no restaurant, no bar and no reception desk in the hotel sense: this is a house, and the experience is closer to renting a well-appointed flat with a spa in the garden than to checking into anything.
Meals and dining
No meals are served. The kitchenettes handle breakfast, coffee and reheating comfortably, and the barbecue and outdoor dining area handle an evening braai, which is the obvious way to eat in here and the reason to stop at a supermarket on the way through.
For anything more ambitious you drive. The Hartbeespoort basin has a broad run of restaurants around the dam, the village and the shoreline decks, most of them within fifteen or twenty minutes, and the summit of the aerial cableway has several places to eat if you are up there anyway. Plan the shopping stop before you arrive rather than after; the steep lanes of Kosmos are not somewhere you want to be reversing out of at nine in the evening looking for milk.
Getting there and getting around
A car is essential, and free private parking is available at the house. Access from the parking to the rooms is by stairs, with no step-free route, so pack accordingly and think hard about heavy luggage as well as about mobility.
Check-in is from 13:00 and check-out is at 10:00. Lanseria, the secondary Johannesburg airport out on the north-western side of the city, is by some margin the easier arrival point; O.R. Tambo means a long transfer across the metropolitan area first. Nothing in the district is reachable on foot from the house, and there is no local public transport, so the car stays central to every plan you make.
What to do nearby
Kosmos sits at the quiet end of a district with an unusual concentration of things to do.
- Chameleon Village and the craft markets, for an easy browsing morning.
- The dam wall and the tunnel cut through the mountain beside it, which is worth the short drive for the engineering alone.
- The elephant and monkey sanctuaries, and the cheetah centre out near De Wildt.
- Sterkfontein Caves and the Maropeng centre in the Cradle of Humankind, east of the basin and a full day out.
- Hot-air ballooning over the Magaliesberg at sunrise, weather permitting.
- The aerial cableway, which stands still on Mondays and Tuesdays and starts lifting at 09:00 on the days it works.
Trade-offs, honestly
The stairs come first, because they are not negotiable. If anyone in your party struggles with steps, this house will not work, and no amount of willingness on the owners’ side changes the topography.
The second is the gap between a kitchenette and a kitchen. A microwave, a kettle, a toaster and a fridge will get you through breakfast and a reheated supper, but a group planning to cook properly for six will find themselves working around the barbecue instead. The third is that the wellness facilities, which are a large part of the appeal, are communal and time-bound — closing at 18:00 rules out the late-evening soak that a hot tub usually implies. Worth knowing before you build a weekend around it.
Before you book
- Check-in from 13:00, check-out at 10:00; minimum age 18 at check-in.
- Pets are not accepted, and bachelor and bachelorette parties are not taken.
- Communal spa facilities run 08:00 to 18:00.
- Access is via stairs; there is no wheelchair access.
- Cancellation terms on some arrangements are non-refundable, so read them before confirming.
- Bring supplies — there is no restaurant, and the kitchenettes are for simple meals.
How it compares
Against a conventional bed and breakfast in the same suburb, this house trades a cooked breakfast and a host at the table for independence, a kitchenette in your room and a sauna in the garden. Against a self-catering cottage on the dam, it trades a full kitchen and a waterline position for elevation, views and the wellness cluster. Against the large hotels and resorts across the basin, it trades facilities and restaurants for privacy and a house of six people rather than sixty. The alternatives across the district are gathered in our Hartbeespoort accommodation listings.
Explore the area
Most visitors pair a stay here with something further west. The North West destination guide explains how the Magaliesberg and Hartbeespoort region sits alongside the province’s safari country, and the Pilanesberg guide covers the malaria-free reserve a couple of hours on. For the city at the other end of the drive, our Gauteng guide is the companion piece.
Current rates and availability
A three-room house fills and empties unpredictably, and what you pay depends on the room, the season, the length of stay and how early you look. Any figure written down here would be out of date before you read it, so check live dates directly for the period you have in mind. If the house is taken, our accommodation finder will show you what else sits in the same part of the basin.
