We were able to book Stefano's apartment last minute the night before we arrived in Florence. The apartment is stylish and has many thoughtful touches (think maps, manual espresso machine with ground beans and tamper, magazines, books, art, bottle of wine on the bed). Stefano is a gentleman, helped us with luggage, offered to book cabs for us to get back to airport, and extremely responsive.
Highly recommended! (thanks again Stefano)
