I go back to the Serena every time I need to go to Nairobi. The location is rather central, but on the very plus side the staff needs a special mention. At reception, restaurant and terrace staff is smiley, serviceable and helpful, just like a good hotel needs to have. For me that makes always the difference. It has also a very good restaurant which serves really good Indian dishes. Gym is good and big swimming pool. Rooms are fine with a fair Kenyan atmosphere. Excellent on business.
