Klara's place is excellently located, you can walk everywhere. There is a Tesco around the corner and loads of really great eating places. Also the tram stop is around the corner.
The apartment is huge - the photo's don't do it justice. While the apartment is spacious it is also very comfortable and sometimes you may just want to stay in!
Sleep quality was excellent with the bedrooms being completely dark and there was no noise.
Maybe the only thing to keep in mind is that there is no elevator so you need to carry your luggage up a few flights of stairs.
I definitely recommend staying at Klara's apartment!
