We had a lovely welcome to Florence- Shiva who works for the host met us at the house and gave us a lot of information which was great. My suggestion is to travel light as there are 3 flights of stairs to climb.
The apartment is central to everything and about 8 minutes from the train station.
The host was so lovely, I happen to leave my phone in the apartment on our last day and shut the door with the keys inside, fortunately she was in the area when we called and came straight over to unlock.
We loved Florence and found our stay very comfortable.
