Not bad, but I would like for them to be more upfront about what you can or cannot do while you are staying there.
For example you can store food in the fridge and also in a cabin they have in the kitchen with a lock, also they can store your lugagge in a room that appears to be the garage which its locked. None of these options are stated in the adds for the booking so you may be planning on carrying the minimum understanding that you can't store things anywere and have a less confortable trip because of this.
Staff is nice, some of them more than others, for the price is not bad but I did not sleep well because the room was hot and dry, but really really dry. Maybe they need to add an humidifier or more ventilation because only after a couple minutes inside, my mouth felt dry as hell.
If you are looking to book this place is because you need the cheapest option and this is the one I found was the cheapest but even if you have 10, 20 euros more to spent for the night I would try to look for something better.
When I went to Barcelona I slept in a similar place, you know, multiple bunk beds in the same room and sleeping with strangers. But this time I paid only 3 more euro per night in similar dates with less anticipation and it was so much better.... I had my own locked drawer which opened with my room kay, everything was newer and nicer... where I want to go with this is that, this place is overpriced even if its the cheapest, I would go somewhere else.
