Ventilation in the bathroom did not work, so in a tiny 16m2 (172sq ft) room, after a short 2-3 minute shower it was slightly wet on the walls in the main room (bedroom). Papers and receipts left in the bedroom were so humid, they curled up after they dried up when I returned home. Nothing dried up during the 2 days I stayed. I notified the staff, and they said they sent a maintenance person while I was out, but when I got back, fan was still non-functional (placed a sheet of toilet paper on the fan, and it fell down with no suction at all).
Another thing. I booked a double room which was said to "Sleeps 4". That's a stretch. Sleeps 2, maximum 2 + a small kid.
Besides this, all staff was very friendly and nice.
