We did not stay at Stipp Hotel Gisenyi Rwanda, but spent half a day using the pool, kids swings and trampoline.
We looked at 3 of the rooms and they were nice, if a little expensive at 70-80,000 RFR (around $130). We also ate lunch here and the food scored 5/5.
Lovely pasta, pomme frites (ok chips) and really tasty chicken brochettes, plus a great side salad, well done to the chef!
There are 3 birds like peacocks that live in the gardens and are nice to watch as they do their rounds.
There is a gorilla waterfall, well equiped gym, large trampoline and some swings for younger children, plus the pool.
The pool has a sudden drop from about 1.25m to 2m as I found out when is slid down the slope and went straight under! Oh and theres a pool slide too.
I would not stay here as I prefer the lodges that are right on the lake, but I would definately recommend the food and if you have young kids they will enjoy the place for a few hours.
Saying that, I prefer this place to the Serena 1/2 mile up the road which is well over-priced and full of people who think they are something special because they pay $200+ per night!
