We had a great stay.
It's worth noting that when we arrived, just after 2pm for our 2pm check-in, the cleaners were still cleaning the accommodation.
They apologised and let us know they'd need another half hour. They finished after 2:40pm. Apparently it's a very busy time of year and cleaning staff are under a lot of pressure.
