I recently stayed at Cristina's apartment for 6 nights with my parents. The apartment is amazing and we couldn't have enjoyed our time in Florence / Cristina's apartment more. It is big (perfect for one or two couples), beautiful, and clean, with a wonderful central location. It has everything you need for your stay. Cristina was a great host. I would unquestionably stay in Cristina's apartment if (when!) I return to Florence.
