Joan's father met us at the appartment as soon as we arrived, although we were later than agreed (we were caught in traffic). We don't speak Spanish so communicated reasonably in French. Everything was clear though and he was very friendly.
The appartment is compact and was VERY clean and SECURE (there is a bolt in the main door that goes through into the floor + also a locked iron gate into the main building).
The location is great, a few minutes outside and you can see the Sagrada Familia. There are small shops, cafes and so on.
