We have just had a 2 night stay at the Welcome Bed & Breakfast In Pisa and I'm happy to report everything was OK. After reading fireman101's report I was quite nervous about staying there as it sounded terrible, but to my surprise the place was quite good. It is on a busy road but there is enough insulation on the windows that you can hardly hear the noise. And to my surprise the windows have fly screens (a rarity in Italy). There are four rooms and two rooms share a bathroom each. Since I traveled with my family I took two rooms therefore we shared the bathroom amongst ourselves. We found wardrobes behind the door of our rooms with plenty of room to hang clothes. I looked outside the window and the bus stop is right there across the road. Yes the attractions are a good hike away but I only paid 60 Euros for each room. We actually had a car and we drove to the Leaning Tower, paid 2 Euros parking for 2 hours and had a good time. The place is actually within walking distance of shops and restaurants. Breakfast consisted of Cereal, cheeses, salami, mortadella, bread, coffee, tea and other various things. We found it quite filling. As for the front door I couldn't open it even with the key. There was a special knack to master which i couldn't but my sons were able to open it and let me in.
