I stayed at Irene's home for a full month while I was in Barcelona and it was the best experience I've ever had. Irene is a great host and was helpful throughout my entire stay. The home is extremely close to a metro station, as well as stores, restaurants, markets, and nightlife. The surrounding area is very safe and I felt completely comfortable during my month in Barcelona. Anything you could need is nearby or available via the metro and the neighborhood itself is very hip and active. If I had the choice, I would most definitely stay here again.
