Everything was fine, the Check-In and Check-Out went smoothly. The flat is located next to a metro station and to a park. You have a lot of small shops around there. The flat was clean and everything (heating, warm water, tv, wifi, ...) worked fine. The hosts were friendly and straightforward. Getting in touch with them was very easy. I got the answers of my emails in a short time. I recommend them for a travel to Barcelona!
