From the accurate information about how to get a taxi from the hotel, to the on-time, courteous and inexpensive airport shuttle, through the unexpectedly well-equipped (single, economy) room, the amazing breakfasts, caring service... I went on business and would return there on holiday.
The pool was lovely, the gym looked great, there is a sun-lounger area above the pool so sun-bathers aren't disturbed by people having meetings around the pool and the restaurant food was just great.
Moreover, for Nairobi, it wasn't too expensive.
And the WiFi works (and is free).
The only caveat is that if you want to get into town, this hotel is quite a way out (in traffic). The up-side is that it's near the airport so you're more likely to catch your plane home!
