It's clean and close to the train station, making it convenient to do a quick 1 day, 1 night tour of Pisa or a few nights of doing train hops to surrounding destinations (Lucca, Cinque Terra...).
This is the ground floor of a residential house complete with fridge/sink/utensils.
They advertise "private bath" which is misleading. It's a shared bath. They accomodate 4 in bunks in one room and there's a Queen in a second bedroom. Then there's another bunk in an open area. If you're there with 8, the 1 bath could be a stretch however when we were there our schedules dovetailed and it wasn't a problem. If you're there with a larger group they had stow-away bed and foamies too.
The neighbour's courtyard backs onto the bedrooms but they were very considerate and shut things down around 10:30.
There's a gate up front. Best to let them know your time of arrival. We were lucky enough to have a cell so I don't know if there's a buzzer on the gate to call them. I think they live on the second floor.
