You can't get a better location in Florence. The apartment is on a corner, literally a few feet from the duomo. The bedroom and kitchen have amazing views of the duomo, and the living room and bedroom 2 face the baptistery. Great birds eye view of all the action in the dome square. This has been my favorite AirBnb I've stayed in. The hosts were also very communicative and quick to reply to any of my messages prior to our arrival.
Pros: The views and location can't be beat!
Cons: We stayed on weekend and weeknights. The weekend nights were very loud on the square until 4:30 am. This wasn't an issue on weeknights, so only a concern if your visit falls on a weekend.
