For all the people staying at the hostel, it didn't feel crowded. It felt more like a community house in an old building with several spaces where one could go to relax if you don't want to be in your room. A large kitchen with a refrigerator where one could keep some food. Free breakfast! The staff was very friendly and helpful. They organize activities every day.
The bathrooms were clean. The rooms have a closet space large enough for you to put your 1 or 2 suitcases, depending on the size (bring a lock).
The computers in the internet room were old and a bit run down and sometimes would not work so bring your own laptop if you can. The room I stayed in faced the street so there is some noise at night (bring some earplugs :-)
Didn't know what to expect and was pleasantly surprised. I would stay here again.
