We had a lovely stay at Sumiyo's apartment in Florence. It was very clean and tidy, just as the pictures show and Sumiyo brought us a change of towels and some rather tasty fresh peaches midweek. The bed was comfy and there is air conditioning. Sumiyo was an excellent host with an excellent knowledge of the city.
The cooking facilities are very useful and there is a supermarket just a few minutes walk away. The apartment has an excellent location, on the southern side of the city just a few minutes walk from Ponte Vecchio and the Duomo area.
We would definitely stay again if we come back!
