What a fantastic apartment and great location in the center of Barcelona!! We will definitely be coming back to Barcelona and look forward to staying at Esther's again. Great communication throughout the stay and Esther met us upon arrival and checked us in and showed us the apartment. The entrance to the building is staffed with an attendant M-F from 8:00am - 8:00pm. All other times the door to the street is locked. There is an elevator. There are only 4 apartments per floor, the building is 6 stories tall, and Esther's apartment is on the 3d floor. The apartment was spotless and is well decorated. There is a sun room at the back of the apartment, that runs the length of the apartment and looks out on an inner courtyard. This lets in plenty of natural light during the day and affords a great reading area. There are windows in the sun room that can be opened for air flow. There are two (2) supermarkets within 2 blocks and many great restaurants within a 5 block radius. Placa de Catalunya, the "heart of Barcelona" is 1/2 a block away, and is a main Metro stop.
