Francis Zandbergen + 5000m | KilimanjaroValkenburg5/56-4-2017We made it and thanks to the height tent. Service is very good, clear and informative. In all likelihood, the effect has been that your body has already been put to work, I slept at 5200 m without any symptoms of illness and I reached the Base Camp Mount Everest. Thanks again! Greetings, Fran
