Since this is hostel, towels and soap,shampoo are not provided. You can "rent" towels for duration of your stay for $Euro 1.5 so cost is very reasonable. I was provided with mini shampoo/soap bottle too but it maybe a good idea to bring it with you.
Stay included breakfast which was pretty good. No warm dishes but buns, bread, cheese, cold cuts, youghurt, etc. Much better than say Continental breakfast in US.
This place has sauna, pool and other facilities. Also mini-bar downstairs.
Very good experience for the price.
