Excellent experience, planning to go back!
Unbeatable location, 15 seconds to Las Ramblas, 7 if you run (we timed it). Fun and cozy, with very friendly English-fluent staffs, ready to advise you with your trip. Normal breakfast (bread, coffee, cereal) and free dinner until the food runs out (usually after 15 mins). Magnetic key for front door, your room and locker in your room. Flamenco show next door, where you can get 50% discount by showing your key. Billiard and cheap bar in common room.
No plug in your room, there is one in the kitchen. Men's bathroom on the 4th floor have no doors except for one. 4-mixed bedroom is pretty much quiet but the 8 tend to get very noisy.
