I stayed here for about a week in an 8-bed dorm because it was the cheapest place I could go to, and I have no regrets. Quite the opposite.
Staff was exceedingly friendly and everything I could ask for was available. Clean rooms, excellent shower, big lockers right by the beds.
Security was absolutely top notch, and in the best way. Reception is 24/7 and has direct eyes on the front door. You need to buzz at the door to be let in, a second buzz to get to the dorms, a key card to get into the room and then there are the aforementioned lockers, for which you can get a padlock basically for free (five euro deposit, you get it back). It sounds like it could be hassle but in the entire week I was never left waiting at the door for more than a couple seconds. I felt safer in this place than any other I've been to.
Yes, the neighbourhood is questionable, which is probably why they have this security to begin with. There's a lot of junkies, hookers and homeless people, and many will try to talk to you to ask for money, or to sell drugs or sex. It can look a bit scary at times, but let me tell you this. I'm a tall, crazy transgender woman who walks around in a miniskirt and without shoes. I attract all the attention I possibly could just by standing around. I walk through the street and all eyes on me. Yet, not once in the whole week have I had a negative experience, other than the casual heckling for money. I took some basic precautions against pickpocketing and not once has anything gone missing. The place is perfectly safe if you use a bit of common sense.
So, all in all, high marks. Loved the place. Will come again.
