We had a wonderful time here. The staff was very friendly and helpful. Especially the hygiene was really good, everything was clean, rooms were cleaned once a day, everything looked sort of new. The kitchen is great, there is a fridge and all sorts of kitchen stuff you can use. There aren't a lot of rooms, which makes it a pretty cosy hostel. It is also located close to the Ramblas (5 min walk).
But, you could hear the traffic through the window, so a set of ear plugs can be helpful. The curtains also still let the light trough, but it helps if you close the window shutters. There is free Wifi, but you have to like their facebook page.
