There were 2 toilets + showers to share between about 30 people in my section. Neither of them locked. Although kitchen facilities were advertised, for some mysterious reason the kitchen was only open from 3pm-10pm every day, so not ideal for sorting out breakfast/lunch. Furthermore, although there were little lockers for important things, you couldn't borrow or rent out the padlock needed so you had to buy one - for 5 euros... The only plus was the baggage room you can use till 9pm on last day.
I did not feel hugely welcome and this made me feel a bit uneasy. Really a shame considering the great location.
Fantastic hostel, couldn't recommend it highly enough!
