The heat is a problem in hotels near airports all through Europe now. It was the same near Heathrow. Windows don't open or if they do just a crack. The air con controls don't work in the winter.
They are set to one hot temp and don't work. Cheap or expensive.
Had the same problem in a Brighton no where near an airport.
And one in Germany.
It was so hot just checking in at a German hotel that people were getting overcome in the very long queue.
The staff behind the desks were overheating as well. They had to open all the front doors and wedge them to keep them open
Apparantly the heat is controlled by a central system in a lot of hotels now. At the German hotel they claimed that in the winter they could not change it to cool.
They say that it can be controlled by the front desk at some hotels but my experience is that it took hours to cool down if at all and i needed to keep ringing every 6 hours as it went back to hot.
It's not just cheap or airport hotels now. I've noticed it as a trend after Covid. Complaints all through Tripadvisor etc.
Also noted all through europe air con just 'failing' in individual rooms for no apparent reason. France most recent example. Same room worked last year. This year no air con. Moved to another room and just an occassonal light breeze if at all.
Are they trying to save money, obey local laws on air con or just not fixing known problems?
