The location is perfect as well as the apartment.
It is situated in a very centre of Florence. The apartment is spacious, well equipped and very clean. You have everything you need - separate kitchen with all the stuff, big bathroom, and a beautiful room with old-time furniture and stained glass windows.
Ale is a perfect host, he was more than pleasant. He provided us with detailed information about everything (map, guides, check-in and check-out info, etc.). He even provided us with some food and coffee :). And he was very careful about our staying.
I would definitely recommend this apartment in Florence.
And I will definitely stay there next time.
Big thanks to Ale!
