Marella's flat is in a perfect location, really easy to walk to most of Florence's attractions. Her friend was there to greet us as we arrived early, and provided really good info and resources for our stay in the city. The kitchen was stocked with some basics that helped during our stay.
The only thing is it gets a little warm in there with the summer heat, but not really unbearable. There is a ceiling fan to help cool the place down.
