My girlfriend and me have slept in this b&b just 2 days ago. It is very very comfortable: big room, big wardrobe, big bathroom, all very clean and very friendly staff, fantastic breakfast! If I'll go to Pisa again someday I'll choose for sure this b&b again!
P.S. I lost my wallet at the airport and mr. Leo offered us a ride to the airport with his car. He has been very kind!
