I would 100% recommend “The Lily”. It’s in a great location, walkable to everything and Francesca, the host, has thought of everything you could possibly need or want in the apartment. Washer/Dryer (takes about 5 hours to do both), bathroom amenities, towels, chilled water, coffee, etc. She even included a guide to the best restaurants and her pizza recommendation was awesome! Francesca has 6 apartments in Florence, you can’t go wrong with her as your host! Highly recommend!
