Elena was a wonderful host and her place is situated in a great neighborhood.
It is very close to a subway station and 3 blocks away from la Basilica Sagrada Familia.
I really enjoyed my stay at Elena’s apartment. The only thing that could be a problem for the light sleeper is the room I stayed in was a little bit noisy from the street. It was not a problem for me but if you need a quiet place to sleep ask her for the room that doesn’t have a balcony :-)
