Excellent, central located, very clean and comfortable! The staff are amazing, they make you feel very welcome. There are many free and fun activieties offered. (Plus extra 10 points to Luis :) Dont miss the bike tour with him!)
I would definitly return and recommend to stay at bed&bike! btw Barcelona is great to explore it by bike!
The ambience at the hostel is great too, cool people from all over the world. I really enjoyed staying there!
