Everything on the island of Venice appears to be expensive or not very good condition (in terms of AirBnBs and hotels), so I believe this to be the next best value alternative! The place was clean and communication was great. The bathrooms are shared but there's two of them so more than sufficient for basic use. Breakfast is something rare in my experience with AirBnB so I'm glad we were welcomed with fresh eggs, sausages, apples, bread and nutella every morning. It's nothing too special but definitely grateful for it!
Transportation-wise, it's very close to the Mestre Station. From there, it'll take a 10 minute commute to Santa Lucia Station and the island. You can also take the Number 2 Bus for a more direct route.
