Me and my family enjoyed a week in Barcelona staying at Arantxa's place. It was a nice and relaxing area and sommetimes we just relaxed in the apartment. There are only one a/c in the apartment that are placed in the living room. Some of the nights were therefore very hot and difficult to sleep. But only when it was very hot outside!
Arantxa was a great host! She wrote recommendations to us many times during the week and helped us finding glutenfree and vegeterian restaurants.
We would definitely consider living there again when we return to Barcelona!
