We stayed at the Peace Guesthouse for one night in July 2012 and we had a nice time at this lovely guesthouse. We had a huge guesthouse with a nice living with a refrigerator and a TV area and 2 bedrooms and a bathroom. Unfortunately the water wasn't warm and the bathroom is a bit old. There was no shower but only a bath and the bathroom wasn't very clean. The staff was very friendly and helpful.
Dinner wasn't very good and we had to wait a lot for our ordered food. Breakfast was ok but the buffet wasn't very rich.
The Houses are dispersed between gardens on the Hotel Ground an directly on the border of Lake Kivu. Nice Location but not all the gardens are well maintained.
Still, if we stay again in the surroundings, we would chose the Peace Guest House again, without any doubt, as it is in a touristy quiet place and you can have a great stay here for a short period of time.
