We stayed at Manuel's house for a week. Manuel is one of the nicest hosts i have met so far. He always answered my requests and was very very nice. The flat is ok but a bit small for 3 people and a baby. I think it is perfect for two, max two people and a baby. Other than that, the flat was clean but not recently refurbished. It has a great location. In summer it is very hot but this is a problem of Barcelona in general, not much can be done. The AC was working, so for those who can stay and sleep with the AC on the top of the head it shouldn't be a problem.
