We stayed there last year for 20 days, problems with the AC the first day, it was too hot we couldn't sleep. We reported it at 11pm and at 01am technicians finally came try to fix it. Long stoy short, we ended up sleeping in an inside cabin that night.
The concierge told me later that all the cabins on deck 3 have that problem, during the cruise we saw that the passengers in the cabin next to us moved out to an upper deck.
That was on the Nautica in June, 2023, the Suez Canal transit from Dubai to Barcelona.
Hope things are fixed by now.
