After check in, turned on the air conditioning unit beginning temperature of 22... After a few hours the temperature had climbed 22..23.. 24.. I had called and spoke with Sergio at the front desk, he had come up to take a look. The unit was indeed on and running full speed.. he simply turned to temperature request to 10 and assured that it will be fine in an hour or two.. it continued to climb 24.. 25.. and 26 by midnight.. I had opened the window to do the best I could to cool the room down, the best I could get it down by in the morning was 23/24. Was unable to sleep, was very uncomfortable and had better stays far out in the low country of Appenzell.. certainly not a city 4 star hotel where I booked the best room they had. Very unpleased, I spoke with Tatiana upon checkout and explained the situation once more. She issued a sincere apology, but was unable to do anything for me since we booked through Expedia. Looking for some assistance please, booking through this service has left me in a position of inconvenience.
