We did enjoy our stay very much. The location was ideal, really close to every one of main sights, the apartment was huge and stylish and it had all the amenities we needed. There were a couple of issues which are not exactly the host’s faults. Firstly, it was really chilly but that won’t be an issue obviously in summer, there is just an Italian law that prohibits to raise temperature above 21 degrees so if you travel in cooler seasons be ready to bring warm pyjamas. The second issue is the noise. You could hear almost everything from the street, especially parties or tourists roaming at night, that lasts long - till 2am on some days for sure. So if you have troubles with falling asleep or you are just generally a light sleeper, keep this in mind.
Well, and the last issue is cleanliness, I found some hairs in the bathroom and the bed linen was not very clean (they were dusty mostly, probably previous guests did not stay in that room) I checked only in one room so that’s maybe one time thing.
Other than that, it was a really pleasant experience. Our host Matteo answered all of our questions or requests very quickly and we enjoyed our stay in Florence.
