Overall my experience staying in Carlo's place is super positive. The location of the place is great in terms of the walking distance to all the major touristy sights and museums in Florence. The aircon is a life-saver in the summer Florence weather as most places in the city have no aircon I was so worried that I wouldn't be able to sleep at night due to the humidity. Also there are so many good-value Italian restaurants around (e.g. il Contadino just 5 mins down the road). Something that's been mentioned by other guests is the noise level from the bar middle of the night right outside of the window across the streets, but mostly I felt harmless as long as you have your door locked. Oh and Carlo is very kind, friendly and helpful who attended to my numerous question at a prompt speed.
