We had a fantastic time at Juan's place.
He was always very friendly and helped us a lot when we had questions. His insider-information about the best places to go to the beach or which way we should take to get to specific places made our stay very comfortable and everything worked out perfectly.
The apartment is cosy and it is near to the metro station from where you can get to all the sightseeing spot of Barcelona in a few minutes.
Muchas gracias!
