Loved our stay in this apartment! It was well-appointed, sunny, quiet, and clean. There's plenty of room and the layout is great in that one bedroom is located in the front and the other is in the back and each has its own bathroom. So you're able to create a little space between you and your traveling companions (if desired!). The neighborhood is quiet, which we appreciated. When you want to jump into the tourist-filled fray, you can either hop in a cab or take a short walk to the Espanya subway station, and jump on a train which will have you in the center of town in no time.
The cost of this rental was very affordable, and the hosts are super responsive. They typically answered my questions within minutes.
On a side note, one of the best meals we had during this visit was at Bodega Amposta which is only one block away.
