Guido was an excellent host. We met the downstairs neighbor, Mr. Lombardi, to retrieve our key, and he is a charming and chatty Italian fellow who made us feel welcome. The apartment is comfortable and spacious, and although it has a few quirks -- the hot water boiler needs to be restarted every so often, and the water temperature goes up and down -- Guido left a detailed guide explaining how everything works. The wifi was rather slow. The location was excellent and very convenient for Florence. We left our bags with Mr. Lombardi after checking out and still had a fun day in the city, picking them up in the evening. Overall a very good stay.
