To start with, the apartment is definitely one of the best in Florence. It was not our first time in this amazing city, my girlfriend has been studying for a year here.
Checking in was perfect, we arrived a little bit later, but Lorenzo has already waited for us and he met us with a smiling :) He helped us with luggage and told everything about apartment, nearby attractions and so on. The view from the window is unbelievable!!! A/C works very good, also for heating. There are a lot of things for cooking, by the way, the nearest supermarket is in 5 minutes.
It will take 10-15 min approximately to get to the Duomo area, passing through amazing Italian shops, restaurants, bars etc.
Summing up, I will definitely recommend this apartment to my friends.
