Really good location, but as often in Italy, you'll got to pay all your stay in cash only on arrival, so, if you stay for a while, prepare the bills. The room with private bathroom is really silent, while the shared bathroom one, is really noisy being in the side of the street.
A really, really nice place to stay. A hostel in the true meaning of the word, you eat with all the other guests, and the food is local, fresh and tasty. The staff is friendly, and the evenings are enjoyable as you get to chat with others travellers around a drink. The place is beatiful, the hostel is alone in a natural park with great view on the city. Wifi works very well, and to PCs are left to the use of the guests. It's easily reacheable by bus + shuttle from the center.
Nice stay, easily reachable from the center by public transportation, clean, nice staff, climatisation efficient, in one word : functional. Just a little tip : the room 30 could get really noisy because the climatisation machinery is on the balcony.
