Stayed in a party of 7 in June 2013 and had a brilliant stay. The apartment was a good size for 7 people (3 rooms + a sofa bed and 2 bathrooms). The apartment was nicely presented and clean. Wi-fi was available and worked well. The location is excellent for the Sagrada Familia (and has a good view), and is close to the metro for other sites in Barcelona. There are bars and restaurants in the street outside the apartment, but it wasn't noisy at night. Elisa was very friendly and helpful so overall I would highly recommend if you are looking for a place in this part of the city. Being on the 5th floor it may not be suitable for parties with mobility issues or young children - there is a lift but it takes only 3 people at a time.

My only word of caution regards pickpockets in Barcelona. One of our group had a wallet stolen on the metro so keep your belongings close!
