Flo's place is really near The Central of Florence, by foot it is about 5 minutes to the leather market or the San Lorenzo Market. U can walk to the SMN Train station too in about 7-10 minutes.
The room we stayed is clean but was a bit small cos we had big luggages so it was abit difficult to open them up. If you have small ones it will be perfectly alright.
Everything else was good and Flo even provided some juice and bread for breakfast!
We had a noisy Neighbour which is our luck...
