Flavio's apartment was fantastic. It is located very, very close to the main pedestrian thoroughfare and within 10-15 minutes walking distance of many major downtown attractions, and is close to public transit too. Though the apartment is small, the space is used wisely, so there's plenty of room for several travelers to share. If you're traveling with several other people and want to stay right in Barcelona's core, this place is an excellent alternative to hostels or hotels.
