I cannot rave about this place enough. It is a stone's throw from the Duomo - you don't get more central than this! All the city's attractions are a short walk away, but the flat is still really quiet in the evenings, so you get a great night's sleep. Azadeh was super helpful for check in, even waiting up for me when my flight was delayed. She showed me all the good restaurants in the area and maps and brochures are all laid out for you when you arrive. The flat is gorgeous and has absolutely everything you need, even mosquito repellent! It's also air conditioned, which is a huge plus if you're travelling in the summer. I was visiting Florence alone and I found the neighbourhood very safe. The flat has a double lock and has a safe, so you feel completely secure. Cannot recommend enough!
