I traveled with my mom to Venice and we stayed for three nights.
Structure/Amenities: The unit is one bedroom apartment with private room and living area located on the first floor off a side street. The kitchen is wide with workable stove, refrigerator and freezer. The bathroom is moderate size with the shower and toilet side by side. There is a television (did not work when we were there, but we didn't need it), wifi, plates, utensils, refrigerator, freezer, stove, hair dryer and two mosquito repelling plugs. Cons: The unit gets hot and there is no fan for the space. There was peeling/flaking paint in the unit. The television did not function. The structure of the bathroom with shower and toilet side by side made using the restroom difficult and caused for small bugs to be present in the bathroom when we arrived. I recommend not walking into the bathroom with shoes and to bring sandals for all use of the bathroom. There were no paper towels or kitchen rags provided, which made self cleaning of kitchen difficult.
Location: The unit has a central location with a 10-15 min walk from the train station, 2 min walk to one super market and 10 min walk to another. Very helpful for purchase of food and mosquito repellent. It is approximately 25 min walk to most tourist sites. Very accessible. It's on the edge of a public square making it close enough to night life and social venues. There is a church close by with the church bells ringing at different parts of the day. Cons: The noise from outside night life and restaurant in front enters the windows making sleep difficult at times. There is a neighbor who plays beautiful guitar, but he enjoys playing out front late at night. Bring ear plugs just in case.
Communication: The host communicated frequently prior to the trip and provided information for the unit. Like most Airbnb units, a third party is hired to help manage the unit. As recommended, I communicated with the third party prior to the trip. Con: It was difficult to locate the specific unit location. Apps provided varying locations. So long as you arrive to Campo Santa Margherita, you're in the right area. We did not hear from third party until just before check in. We waited 1.5 hours for her to arrive and entered the unit late.
