I had an great experience in Hector's place! First of all, Hector is an extremely nice and welcoming person, he makes you feel like visiting a good friend! His flat was perfectly clean and tidy, and is situated in an old Art Nouveau building which adds to the experience. Having in mind that, the room is small (which is typical for older buildings in Barcelona), but it was perfectly enough for a single traveller, and being able to use the living room, I never felt uncomfortable (and after all, being in Barcelona means that you'll spend all your time out). The location is perfect for exploring the city, most of the places of interest being located in a walking distance, as well as the bus stop for the Aerobus and the Sants railway station. So, don't think twice, this is a great place to stay in this outstanding city!
