The only hostel in Siena. However, if you are looking into booking a private room, look elsewhere because I regret paying 40+ euro for a private room here. The private rooms here have no safe, have a bunk bed, is cramped, and overall not the pleasant respite from hostel life that travelers seek. Unfortunately there were also some interesting stains on my blanket which really made me uncomfortable using it.
I recommend either staying in Florence or Pisa and doing a day trip by train to Siena, or staying in a bed and breakfast in Siena itself. This hostel is simply located too far from the city centre, and getting to and fro is anything but convenient as the advertised shuttle wasn't available twice during my visit. read more
