I wonder what's going on that hotels in Barcelona could be sold out so far in advance! This past summer we stayed for a couple of nights at the Atrium Palace www.hotel-atriumpalace.com

Good location , close but not on top of Las Ramblas ( am I the only person in the planet that dislikes Las Ramblas??). I got a pretty good rate in the internet ( approx 130 euros). Just be aware the rooms are small ( although the bath was a good size and very modern).
