Mari is such a delight. Very close to Sagrada Familia and many other areas. Do yourself a favor and don't get paella in the Avenidas close by, instead go to Gracia and go to Taverna el grop. Best paella!!!! Check out Sagrada Familia Bascilla during the afternoon when the sun is shining in and do the audio tour. Wander to the beach by tour bike or on foot. We also loved the old city/el born. Would love to visit again!!! The place is great.
