Sven and Oscar are very helpful and nice, Gracia is one of the best places on earth and the apartment is amazing, but be aware about the fact that this place is located next to a square on which there is an extreme level of noise; It has a festival character, with loud singing, live music and shouting until the early morning. Ear-plugs are a necessary survival tool. There is a second bedroom, to which you can move, if the noise bothers too much. The flat is perfectly fitted to the needs of a traveller, there is nothing that would be missed; though the overall cleanliness is not very high, which I found disappointing because everybody has to pay a extra fee for that, but it is still a great place to stay.
