I had a very nice week in Barcelona with my girlfriend and Romain's house was one of the reasons we liked it.
Although we had some issues with the bathroom and the Barcelona heat, overall, we had a good experience.
The kitty was nice to us, we were treated nice. Highly recommended location if you want to visit the city (very close to important landmarks, within walking distance) and also have some rest. The neighborhood is quiet and well connected to the rest of the city.
Too bad we couldn't talk much with Romain, though we kinda had the entire house for our selves.
