The hostel was the perfect location if like me you visited Pisa to see the tower, it's practically next door to it! Hostel is nice inside with some good communal space including a garden and living room. I stayed in a 6 bed mixed dorm which was adequate. The also had air-con which was much appreciated.
The only downside to the hostel is the fact its only got two bathrooms (at least 10 people to shower + toilet) and with high demand the bathroom become dirty very quickly.
The value of the room is ok and includes the city tax so there is no extra surprise payments. This ideal if your passing through Pisa with the aim of seeing the tower.
