Sergio is an amazing host who goes out of his way to help you have the best experience as possible in Florence. He offers a very nice, clean suite in a great location at an amazing price!
Do note, that the shared hallway does result in some late night noise if other guests are coming/going at odd hours as sound does tend to echo into the room. In addition, though the suite is on the "third floor" for those of us from North America we would call it the fourth floor. That may not be much of a difference to most, but after an extended stay my partner and I were near exhausted by the prospect of climbing up those four flights of stairs and often petered out for a breather on the "second" floor.
Overall, the unit is located in an amazing location and offers exactly what the listing shows - a clean and welcoming space for your stay in Florence.
