Els Verween + 5000m | KilimanjaroErtvelde5/520-12-2016The service was very good, nothing to complain about. By sleeping in the height tent I was able to prepare well for the high altitude and had little or no trouble with the altitude (5900m). While someone else in the group has had a lot of problems with it. He had not slept at high altitude beforehand for acclimatization.
