The communication with Kris was really easy, she organized everything for when we came. The flat was really nice, just like on the pictures. The only trouble was that the rooms are on the street side and with the fiestas de Gracia in the street, it was really noisy. The terrace is actually on the roof, so we didn't go there since you have to go up one floor and use a key.
We really enjoyed our stay and we recommend this flat to anyone who wants to be in the middle of this amazing neighborhood which is Gracia.
