Hôtels Courtyard à Cluj-Napoca

I've stayed well over 1,000 nights in Marriott hotels over the last 20 years & my stay at the Cluj Courtyard was by far the worst experience I have had! We arrived in the hotel pretty late at around 7pm, had a shower & went straight out for dinner, I set the air con to 18deg's before we left as the room was very hot when we arrived. To note there were no instructions on the air con, it was a case of 'trial & error' with the control panel We arrived back at the room at around 10.30pm & the room temperature was showing 25.5deg's 🥵 so I rang to reception to ask what was wrong. I was told that a few adjustments had been made and the room temperature should start to drop so we went to bed. After a couple of hours at around midnight we had to get out of bed as the temperature was just too hot to sleep, it was still showing 25deg's! I was told that the air conditioning must be faulty and there was little that could be done. No fans were available. We did eventually get offered a room across the corridor which he told me would be cooler temperature so I said we would take it just to sleep in. When entering the room across the corridor it was 24deg's but had again been set to 18deg's but we were assured the temperature would drop quickly. We had a cold shower & got into bed although the new room was still very hot. We had a miserable nights sleep with the room being still 23deg's when we left in the morning (it had ran all night set at 18deg's) We had to go back to our original room to pack which was still at 25deg's. The outside temperature that night was 19deg's so both rooms, with the air con on full, were still considerably warmer than the outside temperature! We only really used the hotel to shower & sleep but our experience was terrible & the actual hotel I believe is as good as brand new having only opened a few months ago. The most disappointing thing however is that I have had no communication from the hotel at all since we left. Yes sometimes things go wrong, very, very occasionally things go wrong twice but when as a hotel you know your customers have had an absolutely miserable nights sleep with a combination of multiple phone calls, moving rooms in the middle of the night & little if any actual sleep and you don't even have the decency to apologise makes a terrible stay absolutely shocking! As above, I have spent over 1,000 nights of my life in Marriot hotels and this stay was by far the worst from the one thing that as a hotel you have to get right ie affording your clients a great nights sleep!
