Overall a decent place to stay in Florence. The host is very friendly and welcoming. However, this property is in a quite neighborhood, bit far from the train station Santa Maria Novella. About 23 minutes walk from the main S.M.N train station. This is an important parameter if you want to walk back to the place very late in the night.
Also, it seemed that the doors and walls of the building are bit flimsy because we could hear people speaking and giggling even late in the night in the other rooms when we were trying to get a shut eye.
Its important to check-in before 20:00 hours not to pay an extra sum of 20 EUR.
