I would recommend Moti pearl& Silver bells if you want a place within the town....Moti had an offer the other day 1500/= bed and breakfast I dont know if it is still on.
Siverbells has undergone some very impressive renovation with a modern gym (I left when they were setting up the gym)
Galaxy is about 1km from the town centre I have never been there but I hear its quite good.
If you want a place you can spend with your family in the outskirt of the town I can recommend Gadisa lodge.It has a swimming pool and has a very serene environment...it is run by a muzungu lady who has married a samburu.They have very nice cottages I think they cost 2500 a night.
