Me and my friends visited Barcelona for 3 days. Felix's apartament was perfect for us - located literally next to the Sagrada Familia, in the area full of restaurants and good bars. Exaimple district is aroud 40 minutes by walk from the old town, also good communicated with public transport, around 20 minutes from El Prat airport by taxi. Flat itself nice, simple with all needed equipment. Contact with Felix before and during our stay was very quick.
