I had the opportunity to stay for 3 nights. The apartment location is excellent, easy walking distance to all of Florence's major sights. It is literally only a block from the Ponte Vecchio. A short walk to the Pitti Palace, and the beautiful Boboli Gardens.
There is a very nice grocery shop across the street that sells everything you could need, including high quality fruits and veggies as well as a delicious selection of meats and cheeses and bread. I enjoyed being able to prepare a small breakfast at home before going out for the day. The kitchen is tiny but well equipped for making uncomplicated meals. There is a wonderful gelato shop across the street.
The apartment itself was clean and well organized with modern appliances and fixtures. The bed and pillows were really comfy, and big windows in the bedroom allowed for lovely natural light during the day. If you are a light sleeper you might bring earplugs and an eye mask, even with the curtains drawn at night there was a bit of light from the street coming in. The double-glazed windows did a good job of blocking sounds out, but if you like to open the windows then you can expect to hear a fair amount of street noise.
The only downside of my experience is that the building did have a bad odor which sometimes permeated into the apartment. I was told by my friend who lives in Florence that smells are very common throughout the city due to the septic systems in most buildings. Since this was my first visit to the city I really don't have a point of reference.
Riccardo was an excellent host, and was very responsive and helpful to any questions I had. He even called to arrange a cab to come pick me up on the morning I checked out.
