Overall, great stay in the heart of Florence. the apartment was clean and had everything we needed for a comfortable stay. Lots of space and cool vintage old-school layout especially downstairs.
It was just south of the river so it made the main city center easy to walk to in 10 min or so. A couple things to keep in mind though, if you are coming in by train you will likely be dropped off about 20 minutes walking distance (taxis are difficult in the city and no Uber) from the apartment. It is a nice trek, but it's something to keep in mind if you are coming in with bags likely need a taxi.
Also, as previously mentioned, only AC in the master bedroom and living room upstairs. downstairs stays fairly cool but isn't the same as having AC.
WiFi only works upstairs near the master bedroom not downstairs.
All that said, it was a very comfortable stay with a super smooth check-in process and would be happy to stay again.
