This location was great during the Le Gracia Festival! We were in the perfect location, the apartment was so clean and located near metro transit stations.
During the festival there is loud music that plays late into the night, so this was not a problem during our stay because we went out and participated but if you're looking for a quieter experience, choose somewhere outside of the Gracia neighborhood during the festival.
With that being said, I highly recommend this Airbnb. It was a great find!
