The appartement of Mattheo is very conveniently located 30 min from the center by foot (via a nice walk by the river), especially because parking in the center of Florence is quite tricky (we could luckily park a few streets away).
The accomodation is nice and clean, contains pretty much anything you need for your stay.
Mattheo is a very welcoming host, and his advices on the places to visit/restaurants (the sandwich shop definitely worth it) upon our arrival were very useful. He is also very reachable in case of any questions regarding the time of arrival/leaving.
For the welcome of Mattheo and the location especially, we would definitely recommend this accommodation for a stay in Florence.
