My daughter and I stayed in the 3rd floor apartment for 4 nights: it was really lovely and clean, it had everything we needed and the owner was extremely helpful and accommodating. Fantastic location.
I've just read some of the other reviews - some of them talk about 2 floors: the owner actually has 2 apartments which are beside each other in the same building - one on the 3rd floor and one on the 2nd and 3rd floor. The pictures are the 3rd floor apartment (which is all on one floor), but I had a brief tour of the split-floor apartment as well and it's a similar style/ standard - I'd be happy to stay there too.
I hope this helps to clarify :-).
