I had a great and peaceful sleep (albeit short) on a brief overnight (< 12 hours) before flying out of Barcelona. Getting there and in was no problem, and Constance was nice enough to see me off in the morning! Everything was as advertised. An important note: despite being close to La Rambla, the room was blissfully quiet. Getting to the Aerobús in the morning was super easy -- next time, a longer stay is warranted!
