Switzerland is very hot at present, and our room, despite having something on the wall resembling an air conditioning control, was like an oven, the "air conditioning" just spewing out warm air irrespective of the settings on the wall, to the point it was better to switch it off. Opening the windows however just let the mosquitoes in and the traffic noise (and loud shouty locals at midnight) into the room. And at around 5am the aircraft taking off from Zurich airport start going and the hotel is at the end of the flight path, so a nice wake up call, assuming of course we could sleep through the heat and mosquitoes! Needless to say we've had better hotel experiences......
