This flat was spacious, incredibly clean, and in a marvelous location! I would definitely stay here again when I return to Barcelona. The agent was super friendly and responsive, and the apartment worked flawlessly. Maintenance was happening on the outside of the building during my stay, which I knew in advance, but otherwise there were no issues. One caution: if you're sensitive to late night noise, this might not be the place for you. I was in the back bedroom, which is really dark and great for sleeping, but I still heard noise from the bar below until early hours of the morning. That's probably the case in most of Barcelona though; it's a late night haven.
