The thing I didn't like was that when we arrived, the owner was not on the premises. We had to find out from another B&B in the building that we have to have an appt. for when we arrive or he doesn't show up. (however, the manager did take care of us after I contacted him via phone with no problem at all..FYI, he spoke great English)
The other think I didn't like was the noise of one inconsiderate family in the hall who allowed their child to pound on the ground and walls in the middle of the night upon arrival. It sounded as though the father encouraged the jumping. They were rude! (not the fault of the B&B but just letting you know the rooms are close and you hear the commotion of people entering. If you want a quiet sleep, you may need to go elsewhere. Once the family got to their room, things settled down and I was back asleep without issue! I personally got a good nights sleep even with that incident. This is the first time I shared a bathroom with other guests so it was "different" and I'm not a big fan as some guests are sloppy. The first time we entered the restroom, one of the guests left water all over the entire place and it stunk in there. (but...by the time we returned to the place, the B&B worker had the bathroom all cleaned up and smelling somewhat better!) I personally would stay here again! No major issues that would prevent me from staying. You just have to keep in mind, this is more of a hostel than B&B.
I liked how close it was to the Pisa airport. It's a 4 to 5 minute straight shot walk.
I liked how it was on the bus route and that the Pisa Central Train Station was within a straight shot walking distance! Location was the main thing we were looking for and we got it! I don't know how much better of location you would.
The room was worth the price in my opinion. We had four of us and we slept comfortably in a room of a bunk bed, queen bed and single bad. The space of the room was great. We weren't bumping into each other. The window opened to let in some cool air as well as having a ceiling fan; that was a huge plus!
The other thing I liked was the manager being helpful and letting us into the B&B at 1030 when we arrived. He let us get the key on our own and enter the room. Everything in the room was clean, fresh sheets, no smell...etc.
