My friend and I had a lovely stay at Albert's apartment. Communication was excellent from start to end; Albert was very responsive. His mom welcomed us at the apartment to check us in and was very helpful and kind.
The location is quite convenient. The metro is just steps away, and there's a mini-market next door. My friend and I were out sightseeing most of the time, but when we were at the apartment we enjoyed its roominess (more than enough for two) and that beautiful view of Barcelona. Thank you very much for hosting us, Albert!
