This apartment was great! It has great lighting, it's quiet and the beds are comfortable. It was a great size for the four of us and we could have easily had another person stay and it would not have been crowded. The location was great. We were close to metro stops and went to the bakery/cafe across the street every morning (Teixidó).
We were warmly welcomed and although we never needed to contact Aurélie & Eberhard, we knew they would be responsive.
We'd love to stay there again next time we're in Barcelona.
