I will be in Barcelona for six nights - I am able to stat at Four Points Diagonal for four of those nights for free. See it's about 30 minutes to downtown Barcelona - had anyone stayed here? Is it too far out of the city to be convenient? I would prefer to keep my lodging costs down by staying here - but don't want to ruin the experience to save a few bucks if it's out of the way and not convenient.
Any suggestions are most welcome!
