I stayed in a 4 bed room, it's quite small and bunk beds are very squeeky and you can hear the water running loud in the pipes when the water is running only cons, however really clean, great spacious common room with games and TV, free dinners and bike tours €7. Met alot of people here which was great. Location is great loads of buses and trains available to get you around the city and sagrada familia and arch de triumph both 15 min walk away. Everyone was really friendly and welcoming :)
