The hostel is very nice, everything is clean and comfortable. Each room has giant windows and balconies, so there's enough light and air. The shared toilet is always clean, in the shower room there are shower cabins and toilet too. I found this place pretty for one-two nights.
Lucia will always help you. I asked her to leave luggage in the hostel after check out and she said something like "Of course, it IS your home". That was very nice.
