We had a very good stay in Silvia's place, her husband welcomed us and gave us loads of info about Barcelona, they provided us a baby cot (very attentive).
The only down point is no Internet connection provide (a must nowadays)
Very good location with all amenities and walking distance to metro station and restaurants, etc.
We were recommended to eat at Com Margarit, a restaurant just across the road and it was one of the highlights of our trip, just amazing.
