We just had one night at Lake Jipe
Safari Lodge in Tsavo west national park Kenya, but we really recommend it.
As we just camped here with our own car, we can´t say much about the rooms, but what we saw was really good, spacious cottages with veranda, nicely furnished and the showers with hot water and full pressure (which is not usual in Kenya ;-))
The service was great, Myriam supported us with food (home-baked bread!) for our journey and even could fix our car!
So, if you want to stay away from mass tourism, you will really like this beautiful place in the middle of nowhere.
