There were a couple of things.
We shared a bathroom with our neighbours, but the system was odd and every noise made in the bathroom being able to be overheard!
Every space on the small tables in the room, was filled with items. This is not what visitors want as we wanted space where we could put our things.
Servicing for a stay of 4 nights was inadequate in that our bin was not emptied in the room or kitchen, and no automatic fresh towels, although I would stress that the place was clean and it was great to be able to wash our clothes and we did have a great time chatting to other guests.
