The apartment was very comfortable and beautifully decorated. The most amazing thing about our experience was the welcome we received and the tons of very helpful information about the city, which really enhanced our visit to Barcelona.
The apartment has everything you could possibly need. It is right around the corner from the Sagrada one way and the modernist Hospitat San Pau the other way. It is a metro ride (access by Sagrada), usually with one transfer, to the other points of interest of the city. The neighborhood is not very touristy except right around the Sagrada and does have bakeries, grocery store, restaurants very close by.
