If you plan on visiting La Sagrada Familia, you literally could not do better for lodging. The front door of the building also sits on a pedestrian walkway that is full of restaurants also. I was actually surprised by the high quality dining here, as I expected they would appeal more to tourists. Excellent quality.
Also, at the end of the walkway is the Sant Pau Modernista historic site. It is about a ten minute walk through a tree lined avenue, and much less crowded than La Sagrada Familia. It is s beautiful site that hasn’t really caught on with the throngs of tourists yet.
