Just about everything we could want from a stay in Barcelona. The flat was exactly as advertised, convenient access, flexible staff with office right near the room. Easy and quick walk to the metro, and not a bad walk further downtown if you want to. Vila de Gracia is a great part of town to stay in; we were surprised how much we enjoyed it, and how convenient it was to take the metro everywhere else. 10 minutes and we were right in front of Boqueria and the Gothic Quarter.
Room was clean and well-equipped, with everything we needed to cook and wash our own clothes. We could have been comfortable with several more than the two of us.
If we come back to Barcelona, this is the first place we will look up.
