Maria was very pleasant and the flat was really great with few amazing terraces. The flat was clean and the room was just a bit smaller then we expected.
We knew that there is no air conditioning, BUT the flat is on the last floor and during the night it was super hot (34.4 degrees) and we couldn't even imagine to sleep there. If you are planning to visit Barcelona during the winter it can be a perfect place, but during the other seasons AVOID this for sure!
