Marcel was an spotless host and really helpful, the few times I wrote him for information or doubts, he answered immediately.
The location is perfect, it's just 300m from "Santa Maria Novella" station, also you have the tram which goes to the airport even closer than the station.
You can make laundry and use the kitchen, there are lots of items that you can use for free, even a coffee machine!!
I read some reviews that complain about the noise of the street, but it was not that annoying!
