First of all: The flat is really cute and nicely furnished.
The communication and check-in is easy.
The only bed is a sofa-bed though and this is not very comfortable, I would not recommend it for people with back issues. Cleanliness was not so good. I would expect more from a flat with additional cleaning fees. There is a vacuum cleaner though to clean yourself. But all in all it was a nice stay in a good location.
