Our stay there was really disapointing. We booked with www.iyhf.org. When we arrived, our reservation was writen down, but they were used our rooms for other guest, so they chaged our 2 double rooms for a 4 people room, and They charge us the same amount of money. According to them it was their fault but our "new" room had a "bathroom". Next day they change us to 2 double rooms, one with a big spot of humidity, bad smelling and with sheets full of holes. The other was dry until.... there was a leakage of water from somewhere and all the floor were flooded.
The breakfast was a rip-off, only a tea with some bread with honey and butter or with an omelette.
And if you are thinking about enjoying the roof "restaurant" views, forget it. you can see only the rest of roofs, and they aren´t that beautiful.
Sumarizing: the worse hostel I have ever been in.
