Me and my boyfriend are planning to climb Kili in August via Lemosho Route, with the tour operator Congema Tours and Safaris: www.congemasafaris.com/en/about-congema.html The operator has a very good reputation and their prices are very good, and they become extremely interested for larger groups (4 pers). Please contact me if you are planning to climb Kili in August and would be interested to join.
