Poble-Sec area, the location, cafes-bars, walking around the area at Montjuic was great.
But do not expect much from the house. Sleeping in the room is all right, small, it wasn't a problem for one person, but I didn't feel that I could use the kitchen even to make coffee or tea and also I didn't feel welcomed to spend time in the living room, so I sat in the balcony to eat.
