We have 2 rooms for 4 people (2 bunk beds), and other 2 rooms for 6 people (3 bunk beds), which makes a total of 20 places. If you are not a group of exactly 4 or 6 people, you will have to share room with other people. Each room has its own bathroom. Bed linen and shower towels are not provided, so you must bring it.
There is also a kitchen-dining room, which is shared between all the people lodged in the hostel. There is a fridge, a microwave, ceramic hob, a TV and a table with some chairs. Although it is not equipped with cooking and eating tools, so you must them all (pot, frying pan, forks, spoons, glasses, etc.).
