I had SUCH a wonderful time at Enric & Packo's apartment! I spent 6 days there and enjoyed every minute of it. Located a block away from Sagrada Familia, you have a view of the beautiful icon from the bedroom and the (very small!) rooftop deck. The apartment itself was very clean and efficient with space. Staying there as 1 person was perfect, 2 people would be cozy and any more than that I think you'd be a little bit squeezed. I got a great leg workout as the apartment is on the 4th floor but it's definitely worth the cardio! Enric & Packo provided a cell phone to use while I was in town which was extremely helpful for managing transportation via the TMB app and google maps if you get lost. The location of the apartment itself was very convenient as it was 2 minutes walk from bus, metro, and taxi stands. I highly recommend this apartment and Enric & Packo -they were very sweet, quick to respond when I had questions, and accommodating!
