Organization and availability of the owner was perfect: their service is directly next door and was very kind, helpful and quick to respond. When you book this place we recommend to ask for Gracia 1-1 (with the red sofa on the photos) not 2-1. They are the same size but quite different in style.
Overall a great place to stay in Barcelona: We very much liked the bike rental in the same street and enjoyed Restaurant La Pepita around the corner.
