Fingen's place is super convenient and very stylish. The beds are really comfortable and the rooms are quite bright. We never really had an issue with noise (as some people have mentioned, there is a bar/club below). We did have a small issue with mosquitos, but it was easy enough to handle.
If you're looking for comfort and to treat yourself to a bit of luxury, this place fits the bill nicely. We absolutely would stay again if we were in Florence.
