The heart of Florence is busy, hectic. The opportunity to have access to the classic sites with the ease of a quiet garden residence is really wonderful. I would suggest staying several days in order to use the garden as a lovely respite from the busy streets. I could also propose taking a taxi or public transportation to this place, walking the streets during your stay, and getting a car later if you wish.
The residence is very comfortable with a small kitchen & refrigerator, clean bathroom, places to relax in the garden shade or on the sunny rooftop terrace.
