This is an amazing find in the heart of Florence. The apartment is perfectly situated for typical tourism activities, but also for great food, people watching and nightlife. Marina was an amazing host throughout our stay - offered recommendations, extra amenities, and super quick communications. The private terrace was a delightful refuge from the busy streets below at the end of the day - perfect for a quiet drink at home. The apartment is sizable and comfortable, with a living room and dining space.
Two minor considerations: there is a steep staircase to the bedroom level (others have also commented) - well worth the final nighttime view, but not luggage friendly or easy for people with mobility concerns. Also, there is a rooftop restaurant a few buildings away. On a few nights, it was a little noisy in the bedroom level - but easily remedied with a white noise app.
All this said, I'd stay in this apartment again in a heartbeat. We had an amazing few days in Florence, in no small part due to this charming home base.
