Rita and Gisella's place is as advertised. It is a centrally located, charming apartment, steps away from many Florence attractions and restaurants.
Pro tips. If you are tall you will not have a great time on the mezzanine bedroom there is only a 5 foot 6 inch clearance. The apartment is noisy and the windows shake when a truck passes so if you want a good night's sleep bring some sort of ear protection.
99 cent store down the street is awesome if you're staging for more than a couple of days. Eat at Mangos Fuoco, Simbiosi, and Cloud 59 at least once.
All that being said still worth every penny. The apartment will not disappoint. Enjoy!
