This is a great location and value for your money if you want something that it in a quiet location, yet easy to reach from the train station.
We walked from the train station with our bags (although we could have easily paid somebody to help us with our bags.) It was a short 10-15 walk, and many people do this in Venice. It is not uncommon to see somebody with a wheeled bag.
You can easily walk to all of the main attractions in Venice from here.
Mario and his son Matteo were both communicative and welcoming. The apartment was clean and comfortable, and well furnished. The clothes washer in the bathroom was especially welcome for us. Our trip included additional days in other cities, and we were able to pack lighter because we could wash and re-use our clothes after our stay here.
Overall I would definitely recommend this property to my friends and family, and will stay here again if I take another trip to Venice.
Thanks Mario!
