Very nice apartment with plenty of room and peekaboo view of some of the Sagrada towers. Has just about everything you need for a vacation. Sagrada Familia is very close and we walked to La Padrera and Casa Batllo easily from there as well. If its a couple in one room, I'd suggest the far room further from the stairs for noise and that room doesn't have a split mattresses (two twins pushed together).
We enjoyed our trip very much and found the apartment comfortable and convenient.
