Liked: well equipped, central location, quiet (apart from motorway, which didn’t bother me), freedom that’s not available at a hotel, super communication with staff before arrival, washing machine (I didn’t use though)
Less pleasing: possibly avoid if you’re tall (I’m 185cm) due to slopping ceilings (couldn’t stand up in kitchen or bath), half sized bath (difficult to wash), low door frames (banged head several times), on 3rd floor no lift (didn’t bother me, may bother other people)
