A real gem of a place. Exceptionally convenient location for exploring historic central Florence and the other side of the Arno, also for getting to the train station in <10 minutes by foot for day trips outside of Florence. (We made it to Lucca and Cinque Terre, but lots of other options seem feasible from Santa Maria Novella.) Car rental office also a <10 min walk away. So it's a pretty ideal home base for exploring both Florence and the greater area.
The apartment itself was very clean, comfortable, and functional. Even being on the 5th floor on hot summer days, the A/C worked well and the apartment was very comfortable.
Lastly, the hosts are absolutely wonderful. Very warm, communicative, and responsive. We were met for check-in and received a long list of tips for food and shopping in the area. They also offered to book taxis for us should we need them.
Very highly recommend.
