The first day the staff was not very kind. They gave us a room with an air gap in the wall, a faulty room where the window wall did not close correctly and that 1cm gap made wind noise all night...and they they treated us as exaggerating the issue, I can't imagine it is the first time they hear about it.
I won't be coming back, they offered another room and every floor has some issues with their windows, not that I ever fixated on it except for this time.
Apart from that all was fine, not great.
