Very good location, in Eixample, near the Verdaguer Metro station. Just take the orange and then blue lines to get there from the airport, and you'll pop up in the middle of the city, two blocks away. Check-in was easy, there was a lock box and instructions. If you save a screenshot of the instructions on your phone, you can see everything without needing internet access, and then log in to the wi-fi once inside. Right next to a lovely nursery and giant local market, lots of great (and eclectic) restaurants and bars in the surrounding blocks, and not too far of a walk to any of Park Guell, Sagrada Familia, Arc de Triomf, El Born, La Rambla, or most of the "central" sites. Highly recommended.
