I returned from Kenya this October.
Stayed at the Lion Hill in Nakuru. Nice Lodge, room is a little small, but comfortable. Double bed has mosquito nets. Food is good (typical buffet as other lodges and camps). Nice little veranda in rear of room and can see monkeys there. As for other lodges, ask for room close to reception. Lake Nakuru is different from other parks, especially for the flamingos and other birds in and around the lake. Also good for hippos, close up on white rhinos and gorillas.
Had lunch in the Nairobi Safari Club. Good restaurant and (from the lobby) looks like a modern luxury hotel. It is in the heart of town.
Nairobi is safe in the daytime. It is bustling and the streets are full with people and vehicles (very middle class where you are). As others will tell you (just like other big cities) better safe than sorry at night, unless your ooperator makes the vehicle available (at a cost) for a tour of the city.
Sorry, don't know of the others. Have a great time.
