Arrived at hotel for a three night stay.weather in Prague was very hot. Looking forward to relaxing in my air-conditioned room. However much to my disappointment the room was very hot. Wondering if the a/c needed time to take effect went out for a few hours. Again, with great excitement arrived back at my room.........still VERY HOT!!!!. No A/C. Reported the problem to the receptionist, the solution to this was a fan, upon asking when the A/C would be repaired, I received a vague look and informed nothing would be done until tomorrow. Feeling dehydrated and tired, retired to bed thinking " Tomorrow is a new day!". That morning after losing half my body weight!!!, I enquired at reception what the situation was with repairing the A/C. I was informed the engineer was fixing the A/C. Feeling hopefully, went off for a day's sightseeing. Sadly, upon my return, no A/C and still very hot in room. Once more, enquired at reception and received same explanation. Consequently by check out time the A/C had not been repaired. Very disappointed, would never stay here again.
