A great apartment in an excellent location for experiencing Barcelona! On a quiet street, just off Diagonal, in between Eixample and Vila de Gracia.
The Verdaguer (L5) metro station is just around the corner, and it's 15 mins walk to Sagrada Familia and about 10 mins walk to Pg. de Gracia. There are also some good little bars and tapas places in the neighborhood, as well as the nearby Vila de Gracia.
Apartment is very spacious and the photos on the listing are very accurate. The apartment is fairly basic, but clean and in decent shape. The beds were comfy and the bedrooms facing the street didn't get too much noise in the morning. Wifi seemed to work well throughout the apartment. My only criticism would be the lack of anywhere to hang up towels when in the bathrooms - would be so easy to put up a few hooks!
The communication with the host was good and the lady in the office downstairs was very friendly and helpful. They also let us do a late check-out (5pm for 50 EUR), which made our final day less stressful.
Would stay there again if visiting with a large group of friends.
