This airbnb residence is legit. The room was extremely clean and well decorated, very nice for a couple spending time in Florence. Samuel was prompt in meeting us out front of the building and gave us a great rundown of all of the necessary sights to see in Florence along with a map where he highlited each of the attractions. He also provided restaurant advice and Yellow Bar was very delicious.
The residence is right next to Duomo and very near many great places to visit. My girlfriend and I highly recommend this airbnb.
