The location is perfect. You only need to walk for no more than 8 minutes from the train station to the house. You can also walk to most of the tourist attractions like Florence cathedral within no more than 10 minutes.
The room space is large enough including a kitchen, a bathroom and a bedroom. They also provide coffee machine and microwave. Everything is sparkling clean and the air conditioner works really well ; )
I would definitely recommend this house if you want to find a comfort and convenient place to stay a couple of days in Florence.
