The apartment is absolutely gorgeous with amazing decorative touches throughout. The building is safe and the apartment is at the very top floor (lots of stairs to climb). However, this area is EXTREMELY touristy. It's in a square full of tourist trap style restaurants and right next to a day market with mainly leather goods but definitely has a swap meet feel to it. The host recommended we try Restaurant Za-Za and that it was he best restaurant in Florence so we took her word for it and did but it was AWFUL. All of the restaurants in the square are terrible so if you want authentic Italian, definitely venture out.
If you're looking for a super central location to tourist attractions and subpar food options then this place is great.
If you're looking for a more authentic Italian experience I recommend you cross over the river to find a place. There's jazz cafes, craft cocktail bars and more interesting neighborhoods.
