Emilia and Luis's apartment can easily accommodate 4 people, and is located in the best spot in Barcelona in my view. We interacted with Luis. He is very nice. Our check-in went very smoothly and promptly. It is located on the edge of Vila de Gracia, at a walking distance from the Sagrada Familia (10 minutes) and the harbor neighborhoods (between 20 to 40 miuntes) and Parc Güell (25 minutes). Vila de Gracia was a wonderful revelation to us. The Abaceria market is 5 minutes away. It may be surprising but we thought the café and tapas bar (at the northern entrance) had the best coffee in Barcelona. Ask for café con leche corto!
