For a hostel, it's not bad. I had a shared room with 8 people. The rooms and beds were clean. They provide a sheet, pillow and duvet. There's a safe in your bed cubicle, along with two usb ports & one electric socket. There is also a curtain to provide you with some privacy, and a light. There are also lockers in the rooms for which you need your own lock. Towels are available with a deposit of €10.
The bathroom is a biittt small, but it's usable. I appreciated that there was a bathroom and shower in the shared room. The toilet is separate from the shower. Like others have said - there is no tap/sink in the toilet so you have to go to the shower room to wash your hands.
There's a communal kitchen downstairs, as well as a bar.
The hostel is located close to 2 metro stations that take you straight into the city. The area is nice. I arrived very late on a Saturday night and restaurants were still open, people were out and about and I didn't feel unsafe. There was a market on Tuesday morning just outside - not sure if this happens every week, but lovely to walk through.
