Kaveh's apartment was very nice and comfortable. My husband and I had great nights sleep in the bed and the bedroom even had plenty of room to store our suitcases and hang our clothes. The location of this apartment is a five or ten min walk to La Pedrera and 15-20 to Casa Batllo. The apartment is also fairly quite in the day and even at night.
If we travel to Barcelona again, we would try to stay here. Keveh is a wonderful host, he went out of his way to come back across town to let us in when we ran late getting to the apartment. The pictures online are right on point.
