We stayed at Laura's apartment for 4 nights. Laura and Marco are very friendly people and have two lovely cats. They always asked us if we need something and advised us about different sightseeing experiences in Firenze. Their apartment is about 3km away from the city center and using bus is preferable than walking, especially when it's hot on the outside.
The room has everything that is necessary for a short stay - there is a separate bathroom for the guests, there's a TV, an air-conditioner (which is a bit noisy, but it's better than nothing) and a fridge in the room and the bed is comfortable. Laura and Marco were also leaving goods in our fridge in order to enjoy a quick breakfast in the mornings. Our only remark is that it wasn't that quiet and we were hearing almost every sound coming from the neighbors and from the street. We also had to deal with a few mosquitoes in the room, but that wasn't much of an issue.
In overall, we enjoyed our stay at Laura's place and would recommend it to everyone going to Firenze.
