We can highly recommend this apartment. The two double bedrooms (one mezzanine) and bunk beds easily accommodated our family of five and the space and facilities were more than adequate for us and very good value. The garden outside was a welcome addition though we didn't spend much time there truth be told (the air-con inside proving to be a bigger draw).
Located on Avinguda Diagonal less than five minutes walking from Sagrada Familia (and Metro), and another Metro station (Monumental) less than 200m from the door, the location is fantastic for exploring the city. Situated at the rear of the building ond the ground floor, it also enjoys peace and quiet.
Local shops - head for the Condis, 300m away, for a small good value supermarket, and a very good value Colombian bar next door. We had a good meal too at Xamfra Gaudi mid-way between the apartment and Sagrada Familia.
Esther and Toni were great hosts. Everything we needed was in the apartment and responses to queries were answered very promptly. Highly recommended.
