I'd heard about this place for years and wanted to check it out. It's definitely a "notch up" from other back-packer rated places I've stayed at. I came here with friends for two nights. It's set up for a younger crowd but we did very well here. As long as you know what to expect I don't think you'll be disappointed, especially with the deluxe tents. The location is really hard to find and I know the area. Once the new road is finished I think it will be much easier but meanwhile I'd suggest organising a transfer with the establishment. Of course it would have helped if we brought the map and phone number with us but thank goodness for internet on the phone. Once we got a hold of them their directions were perfect and fortunately it was still daytime.
On arrival there was one person who seemed to be doing everything, reception, waiting tables, tending bar etc. so our check-in was a bit lengthy as in the middle of taking care of us other guests would demand his attention and order a drink so he'd get them their drinks then turn back to our reception. However, this is normal in East Africa but there should have been more staff on hand IMO. On the following mornings there were more servers around. Food was ok, there's a basic breakfast included and reasonably priced add-ons of eggs, porridge etc. The yogurt and fruit were very good. You get one pot of tea or carafe of pressed coffee and then pay for additional. First night we opted for an a-la-carte dinner which turned out to be standard pub food and enjoyable. Dining on the deck is nice. The landscaping and settings are very well done, the "water hole" was quite low while we were there as it was the end of the dry season but it's a nice touch.
The tent was great, set on a wood deck with nice furnishings, there is one king sized bed and one twin bed in the corner. Plenty of space for luggage and a safe which was a real bonus. Excellent hot water, I believe solar heated. The tents are very well made with a nice veranda but REALLY close together so you hear your neighbor's conversations with ease. We didn't have a look at the other type of accommodation or camping area so I can't comment on those. In chatting with the owner he did say the tents were very popular and he would most likely be adding more.
I agree with the previous comment about the kid's toys on the paths. I realise it's a family owned venture and I like kids, but I almost tripped over one of them; paths in a public place should be kept clear. On the whole if you want a slightly different experience, opportunity to connect with younger travellers and want to stay on the Langatta/Karen side of Nairobi this is a good, lesser expensive option. If you need access to city centre or the shuttle bus points to Tanzania it might be easier to stay closer in.
