I booked a 6-person room in this hostel only for one night because we dropped by to Pisa only to see the Tower (nothing else there to be seen) and we were all a bit disappointed with the quality of the hostel and the service. To start with, when booking the room I marked that I wanted to check in at 9 pm and when we found the hostel (it's 2 min walk from the station) we found out that the owner had to drive from her own place somewhere else to complete the formalities. When I called her, she asked if I could wait until "after dinner" which finally meant another hour. Considering we had only one night in Pisa, this was nothing else than a theft of time. When the owner finally arrived, she showed me my 6-prs room.. In fact there were only four beds and one small pulled out of a wardrobe but it was rather for a child than for an adult. The lady told me that the double bed was for 3 persons (for God's sake, who sleeps with 3 people in one bed?!) so I'd rather say there were 4.5 beds. The bathrooms were dirty so I wouldn't encourage anyone to take a shower there. Luckily it was only one night and what we cared about was the location.. But I can't recommend this hostel to anyone. My tip: if you decide for it anyway, mark that you want to arrive two hours earlier than you intend to, maybe then you won't loose time for the check-in.
