My wife and I had a great time staying at Barbara's place in Florence. Convenient location just across the plaza from train station (which was perfect since it was raining when we arrived!), and about 15-20 min walk from most of the main attractions (ie Duomo, Uffizi, etc). Right above a well-stocked grocery store. The windows do not isolate sound very well, and the location is obviously busy and can be loud, though was not an issue for us since we're both sound sleepers.
AC units worked very well. Provided Moka pot and coffee was a nice touch. Rare separate stacked washer and dryer units worked very well and was very convenient. Self check-in worked well, though the building door works in a peculiar way, so read the instructions carefully.
Overall a plain but convenient AirBnb that has all the essentials and was great for our short stay in Florence--thank you!
