This will probably be the best Airbnb that you stay in. The location in Florence is ideal, walking distance to the train station and to everywhere in the city center. The apartment has been updated recently and attention has been paid to all the details. So many little details have been attended to - when you arrive, you will immediately appreciate them all. Do not hesitate to stay here. Small things that you should know before you stay here - it is there is one flight of stairs to the apartment. Not a problem if you can do stairs but if you can't... The shower (like most in Italian apartments) is small. If you are a big person and if shower space is important to you,you want to know.
Other great stuff to know: there is a dryer! If you are travelling for more than a week, you likely are doing laundry. Having a dryer was wonderful. There is A LOT of hot water! I'm not sure if there is a continuous water heater but we never ran out of hot water. After a long day touring the city, a shower without rushing to beat the cold water was such a treat. Every other place we stayed in Italy had a very small water heater.
There are so many other good things about this place I could go on an on... If this apartment is open in the timeframe you are looking to stay in Florence, book it quickly - you won't regret it!
