Cosimo’s place was just perfect for our 4 day stay in Florence. It was close enough to all the sights but still removed enough to make you feel like a local. It was maybe a 10-15 min walk from SMN train station and a 5 min walk to Mercado Centrale. The bathroom was very clean, but please note you are only provided one roll of toilet paper. We brought one roll with us.
Having the washer was also nice. You get one detergent pod.
There’s a grocery store a few blocks away where we got some beverages to enjoy on the rooftop patio (lovely!).
