Very easy to get to public transportation. However, if you're up to walking, it's a +/- 12 minute walk to the Mestre train station. You have all the food you need at his brother's restaurant on the ground floor for very reasonable (European) prices.
He made and provided, for his guests, reference documents showing where to eat and visit in Venice. Despite the personalized information, he took the time to sit down and explain all the details to my wife and myself. The room was clean and spacious. The bathroom was recently renovated. The small fridge is shared and just outside the hallway. The building is secure and we were happy about that.
If you're looking for a well situated, convenient and very reasonably priced accommodation, then you'll do well to book a reservation with Oscar
