The Tribe is and does feel like a real anomaly in Nairobi.
Let me start off positively and say this place is great - ultra comtemporary-chic, modern, new and actually very tasteful indeed. The service and staff are all bang-on and attentive unlike many in African (or less modern) citiies who appear to have to escalate anything more than a 'good morning sir' to their management.
Now, to explain my title above. So yes, the first impression is great. And it lasts. Everything is new, shiny, tasteful, in good order. Even though this hotel is a little remote from most of the interesting parts of Nairobi (in Karen) - this doesnt matter, because this place is all you really need. Lavish (almost overdone, but not quite) decor. Amazing beds and duvets and pillows - best sleep for ages.
The 'Holiday Inn' feel however describes the fact that the walls are thin. You can hear next door if they speak. You can hear next door (or any door nearby) closing at night as it's guest retires. In other words - all this luxury but WITHOUT a solid feel to it.
That said, it is a perfect place to become a hermit for a few days. I personally left the Masai Mara early with my wife, due to an urgent medical condition. After a night in Karen hospital (write this name down in case you need medical assistance in Nairobi - they're excellent) we retired here, and it was a great place to recuperate and rest.
A little cold (August) to use their pool, however it was just as nice to look at (from our room window or trendy little rooftop bar) with it's blue neon edging, pillars rising into the air, in-pool seating and bar, gushing waterful etc.
Once again on the service - we got a fairly poor room service meal (the food/room service isn't bad but not 'great' either) which was quickly collected and replaced by another order of our choice - all at no charge at all. That shows a place that knows service - don't quibble with the guest, dont let guests get annoyed by something that may cost only $10 to the hotel vs you ever coming back again.
This extended to the minibar - all of its initial contents were free - you only pay for top-ups thereafter. Can't say fairer than that, and that itself is a nice touch and pretty rare.
And so it should be for a total of around $320 USD per night. Not cheap by any means.
You're paying for the ambiance. The immaculate set of several hundred+DVDs (all foreign copies by the way, all of which didnt work in the TV/DVD player in the room, but did luckily on my laptop) that you can 'hire' at no charge, alongside the small library of books - all similarly unthumbed and new looking. You're paying for the furniture, the art, the lighting, the water features, the over-the-top decor which, to be honest, is actually very tasteful and luxurious.
Dislikes: the bathroom is part of the bedroom, so even the closest of couples will have to prepare themselves for the sight of their significant other taking a crap through the mostly translucent glass. Even the bathroom itself has no separation from the bedroom (Tribe - a slide door would be good!), so from the bed the whole room just looks like - well, a bathroom. All nicely fitted mind, very modern.
In summary, stay here if you happen to find yourself in Nairobi for a few days (why would you want to be there any longer anyway?) and have a large wallet. There's also a nice place to buy African gifts and trade at the masai roof market just 50 metres away every friday.
