There were some pros and cons with this place and it may not be for everyone.
There was subpar communication with the host regarding booking a direct water taxi to the airport. The host confirmed it but did not pass along any confirmation info or phone # so when the taxi did not show up, we had little recourse other than to get one ourselves. It was very stressful since it was in the early morning hours (3am) and no one was around. Therefore I highly recommend calling a taxi company yourself instead of relying on the host. After our taxi did not show up, my husband was able to call a company and got one within 5 minutes.
Pro: This apartment was in a great location. It was a quick walk to the main sites and the vapretto station but on a quiet (and wide) street.
Pro: Authentic charm
Pro: Spacious, though the slope of the ceilings in the bedroom means most of that is space unusable
Con: The low wooden beams, a metal beam in the shower and the height of the shower head will be difficult if you are over 6 feet tall.
Con: The bed consists of two singles put together. Unless you stay perfectly on each side (and away from the middle) it becomes very uncomfortable.
Con: We were there in October when the temps were 50-65 throughout the day. The mosquitos were out of control. We have no idea how they were getting into the apartment but in a single day we killed dozens (after they bit us all over our arms and face (seriously!) while we were sleeping. I am talking +20 bites per person). It was excessive to the point that I did not enjoy my stay at this apartment. Our Airbnb in Florence included a mosquito net for the bed and anyplace that has a mosquito problem should do the same.
Also- If you do stay at this apartment, do not rely on Google Maps to find your way to the apartment; it sends you to an incorrect location. Instead just drop/save a pin on Google Maps once you are in front of the place.
