Casa Gracia is a beautiful hostel! It's located in a superb location - right among many examples of Gaudi's "modernista" architecture. And, it's very quaint in its decor (charming old chairs, trunks, and other such pieces). My only complaints would be a lack of washrooms (only one, generally, on each floor), and there was a weird smell in the hallways (maybe due to some cleaning product?) Anyway, I had a nice time overall, and I would happily recommend the place to others!
