My stay was wonderful. Francesca met me outside the apartment, walked me through it, went over a map of Florence with me, made many restaurant suggestions, and even helped me find a place to get a manicure. She is so nice, communicative and helpful. The apartment is clean and beautiful. The bed is very comfortable. I was pleased to see that so much was available for use in the apartment (washer, laundry soap, kitchen dishes, tea, blow dryer, towels, etc). I was traveling solo and I felt safe with all the locked doors. I took a taxi from the train station with my heavy backpack, but it is a walkable distance. The duomo and the Galleria dell'Accademia are so close to the apartment. You can walk to pretty much anywhere you want to go. There is a bus stop by the apartment and a taxi stop just down the block.
(I read a review on this apartment before I booked that said it is really noisy. Yes, the street noise is loud even late into the night but that is not the fault of this Airbnb. It is city noise that cannot be stopped so if you are a real light sleeper, staying here may not be for you.)
