If you want to feel Pisa this is your best choice.
Pros: First of all the owners are so kind. They offered me cold water upon arrival and for a small tax he drove me to the airport (at 4:30 am). They also give you advice on how not to be fooled. Very clean, pleasant and comfortable bed and nice pillows. Clean bathroom. Close to tower of Pisa. Surrounded by restaurants and terraces. Cons: It is an old building so expect it to be less than soundproof. They could use some softer towels
