Frederic's place is lovely, bright, airy and in my opinion a perfect place for groups to stay at should they visit Barcelona. His colleague Gianni actually welcomed us in (as Frederic was busy) and took us around the flat explaining the amenities and a guide of Barcelona, including places to eat, visit and transport links. We had a wonderful stay here, the location is so close to Sagrada Familia and a short walk to a couple of Metro stops which can take you pretty much anywhere you need to in short times. I would highly recommend here and would hope to stay here again when we visit Barcelona!
