We did enjoy our stay in Ferran's place. The flat is quite central (close to metro Paral.lel) and easily accessible from the airport. The flat is nice, agreeable, clean, quiet. The pictures show exactly how the flat is. Once in Barcelona, we almost did everything by foot, which is very convenient. In the area of the flat, you can find super tasty tapas.
In brief, we were really glad to choose this flat! :)

Ferran is a lovely dynamic respectful person! He was really kind and supportive during the whole process. I thank him a lot because we felt at ease when we met him on our first day. He helped us find our way around and indicated several places to go, to visit, to see. When you arrive in a new city, in a new culture, it is highly appreciated to have some insights.

That is why I do recommend to stay there if you want to visit Barcelona! :)
