This hotel was gorgeous. Its a shame it took us so long to find it. The hotel does not have a reception and you have to call when you are close to arrival. We did this but missed each other for approx 2 hours which was very frustrating.

Its in a good location and close to eateries and bars.

Lovely decor and brekkie included (with others B&B style).

We stayed at this B&B for one night, which was perfect. I chose it for its location because we were going to be arriving by train late in the evening and because the rate for a quadruple room was relatively reasonable (90 EUR). In the end we arrived around 7.30 on a rainy night and I was glad for the proximity to the train station but I have to say the neighborhood is a little seedy at night, so if you're easily spooked don't stay here. The quadruple room is at the top of a very narrow set of stairs and, as other visitors have said, it can be very clumsy with a big suitcase (ours is medium and it was hard). The room is not large but it is perfectly adequate, with good heating, good insulation, plenty of towels and hot water, shampoo and soap, good bedding, a small TV, a closet and a hair dryer. It was clean and comfortable. It all looked much nicer in the daylight especially after being fed a very nice and varied breakfast: homemade cakes and jam, good coffee, yogurt, toasts, cereal, cold cuts, etc.
Best of all, the attendant and, especially, the owner, were vey nice and helpful. They entrusted us with the house key so we could come back later to retrieve our luggage and use the bathroom, recommended good places to eat and told us how to get to the airport.

ps. it is true the elevator is noisy. Don't stay here if you are easily disturbed by noise.

We were spending one night only in Pisa to complete our honeymoon. Booked Cavalieri 6 months in advance. Arrived to find we'd been double booked. After much confusion we were transferred to nearby property in the same chain - the Harlequin. We arrived to find a child running around in underwear. No discount was offered. Small room not a problem but it had a pervading smell of damp. Room was very sad with a 5 armed chandelier with only one bulb working and a carpet with a huge hole in it. Breakfast disgusting - half eaten apple going mouldy in a bowl, jam that looked to be fermenting, a dog bone under the table (I kid you not!), piles of laundry lying around and every surface covered in either nick-nacks or dust! Staff mostly disinterested. Delighted to escape. Would NEVER recommend this group of B&B's.

We were instructed to call the owners 30 minutes before arriving to arrange to pick up the keys. However, neither of the two phone numbers they gave us worked from my cell phone: one was automatically rejected and one number called a restaurant or a bar or some other loud place. We even tried the first number on a pay phone thinking that maybe there was a problem with my cell phone. However, we were never able to contact the owners and had to find another place to stay. And, we lost our 29 euro deposit.
If you decide to try this place out -- it looks nice from the photos on their web site -- be aware that the B&B is located about 200m from the train station and from there you can take a bus to the Leaning Tower. The hotel is about 20-30 minutes walking distance from the tower.
