Have visited Barcelona several times and stayed in different areas, Rosa's apartment is a perfect location!! You can easily walk to different neighborhoods and if needed the metro line is very close by. The Square that is near by has a lot of action going on but you don't hear any noise while in the apartment. Yes, there are several flights of stairs ( I think we counted 90-100 steps) however, it was a great way to work of all the amazing food and drink we had:) Apartment is cozy perfect for the 3 of us and we enjoyed our private rooftop for an early morning coffee or a glass of wine before dinner.
