Lovely stay. The neighbourhood is lively without being over the top. You can find everything you need within a couple of blocks. Great restaurants and bars in the area too. Joan and his associates communicated with us very clearly. They even arranged for a cab to pick us up from the airport. Would likely stay here again when next in Barcelona.
Note: The apartment is on the 2nd floor with a narrow staircase and no elevator. This can be an issue for people with mobility issues or with a lot of luggage. Also, you can hear the street noise in the night (like any other big city), so if you are a light sleeper it may not be the best. These are not deal-breakers but should be kept in mind.
