We had a great one night stay in Guglielmos apartment. He was there on time to greet us (beware of the street numbering system of red for business and red for residential - which caught us out). He was very helpful in explaining the workings of the apartment and the facilities in the area. It was very convenient to be able to walk to everything we wanted to see in Florence. I would recommend the stay to anyone - although you must be able to walk up 6 flights of stairs.
