Duurzame hotels in Kloten

"This is advertised as a "4 star premium hotel". We weren't expecting a 2 star experience with outdated rooms which lacked air conditioning, not even air circulation. The staff was friendly and happy to assist, but they couldn't resolve the issues. We were given a mini fan by the janitor. We asked for another room, it was full. The next day we got another room but there it was the same. After moving to yet another room with the same issue, we gave up. Funny thing is: when you enter the lobby, everything is cool and smells nice. Nothing compared to the rooms where the guests actually are staying. The showers in the various rooms all had limescale and were leaking, so it seems structural."
