The house was clean and looking as in the pictures. We were 8 and we rent this flat and the another one two floors above (Apartment with "The Guinness View") The problem is that this flat in particular is no very good for 4 adults: we run out of hot water after one and a half shower and the tank did not refilled. The sofa-bed was full of mold and although Christian came as soon as we called, he told us that “in his opinion” they were not dangerous, but the thing is not only that... Also is about how pleasant could be to sleep in a mattress with mold very close to you...
The alternative option were very thin mattresses with a lot of springs which at the end made our stay very uncomfortable. Definitely not repeating :(
