Great location to visit Pisa. Even very clean, our room had some broken elements to fix. The reading lights on both sides of the bed were not working. The air conditioning was totally dead, therefore we had to keep the windows opened during the night. As there was no insect net, many mosquitos were staying in the room, turning around our heads when we were trying to sleep, and bitting us many times during the night. Finally, the sound isolation between rooms was ok but not with the corridor. We were awaken by any move or conversation during the night.
Also, as check out was in the morning and our train late afternoon, the staff kindly agreed to keep our big luggage. However, we realized that they did let it in the corridor (not in a locked and safe area), and nobody asked if it was ours when we took it back (letting us think that anybody with bad intention could have taken it).
