My husband and I stayed here for 10 days this December. From the beginning communication was great, and they even let us check in early as our flight arrived at 9 am and the room was available. That was a blessing as we had just flown all night and we were exhausted.
The woman who checked us in was very helpful showing us a map of the city and showing us places to eat and shop etc. The location is perfect, we were about a 5 minute walk to the city center as well as the Arno river. Florence is definitely a walkable city.
The room was very clean and modern, had everything you’d need for your stay. The only downside was the key you use to get in turns the power on so if one person wants to go out and they take the keys, you are left with no power. Apparently electricity is very expensive in Italy though so we took that into account for sure.
I also messed up on how many nights we would be staying and they were able to change my reservation to accommodate which was great.
Overall would recommend staying her for your Florence vacation!
