Nadim is a friendly and welcoming host who went above and beyond to ensure I was looked after during check-in. He is also an expert on local eateries and his recommendations are excellent!
I stayed in Florence here for one month and was incredibly happy with the location. You're walking distance from everything in the CBD and very close to the public transport network for anything further out of town.
Like many historic houses in the heart of Florence, the apartment does have a bit of character. The stairs really are impressively steep and be prepared for a quick run down of how everything works when you arrive. (There are helpful posters stuck to anything important to help you.) It won't feel like a hotel room, but if what you want is an authentic stay, then this is absolutely the place for you.
The apartment is also exceptionally well equipped, with just about anything you might need - from the useful stepladder to the adorable tiny Moka pot. If there's anything you need, just ask Nadim as chances are it's tucked into some nook in the apartment already.
