I spent a great week : the apartment is very convenient, especially the kitchen and the private terrace as a "bonus", perfect for the smokers. The bedroom can be a bit cold in winter, but there are enough heaters to keep it warm! The apartment is very well located, near the historical center, and there are plenty of shops and restaurants in the surroundings.
Salvatore is a perfect host and welcomes you with all the information you may need and is always ready to listen to any question, or just have a chat: I strongly recommend Salvatore's apartment to anyone visiting Firenze!
