    There weren’t enough lockers for all guests, so I wasn’t comfortable about my things being safe.

    Nice spot, A/C didn’t work so well and the walls are very thin. But! For 13€ I was pleased :)

    I only stay for one night, but it was actually fair compared to what I paid. The guy at the reception was nice and helped me with my bags upstairs, but the guy doing the night shift was kind of grumpy and got mad because we wanted to turn on the light from the common area room for a while just because we were having dinner. Overall it was a pleasant stay.

    One of the receptionists, Israel, went above and beyond in helping me and making my time in Madrid so enjoyable. He seems like such an overall, really great person which made the atmosphere and environment that much better.

    We only stayed two nights. The receptionist was very kind and put us in a smaller dorm that what we had initially or what we had paid for. The hostel is clean and tidy, though it is very old and could do with some repairing on walls and floors. Anyway, we always had hot water, the breakfast is included in the price and the receptionists are very helpful and friendly (24 hours reception). The location is quite good, as the street is quiet during night time but very near from the city centre.

    A nice hostel that provides the basics, WiFi connection was on and off, breakfast was basic but enough. The bathrooms were nice because they were individual rooms for both the shower and the toilet. Very clean hostel, although the cleaners would be there during breakfast and it made it a bit awkward if you stayed in until 12pm before leaving as you would have to move around the cleaners. Receptionists were enjoyable to interact with.

    To resume, great location, never felt insecure, and the staff mainly Israel was always friendly and helpful, it is clean but the facilities really could get some renovation, and the shower didn't have the support so I had to always, hold is myself, and that's too bad because the building is pretty cool actually, if you can get the room that faces the street

    Overall an okay hostel. The hostel is kind of difficult to find considering there is no sign. The door is labeled with the name of the hostel but it sits a bit back from the street so it's easy to miss. The staff are nice enough but don't expect anything from them unless you have checked in. You also have to pay if you want to stay even 30 minutes after check out. There are security cameras everywhere but I didn't feel reassured by that. The rooms were cramped and you need your own lock.
