This is a bedsittingroom/efficiency apartment on the ground floor of the most family section of Venice. I was traveling with two boys, and it was everything they could hope for - a bunk bed, shops nearby (a vegetable seller right next door), restaurants around the corner (pizza!). I was quite comfortable as well.
Since it's on the ground floor, in Venice, there is rising damp in the foundations of the building, but there is a dehumidifier which you should use while you're in the flat, and you can also open the windows. It was not all that noticeable inside the flat, but it's always a thing in Venice, and Nello has provided solutions.
The flat was not fancy, but cheap digs for tourists with children who want to spend time in Venice without blowing the budget. Sant'Elena is a family island, and there is a good playground across the park, and several more on the walk to Via Garibaldi, where there's a Coop grocery store and many other shops. A 3-day vaporetto pass was good, but frankly we walked into town and only used the vaporetto when we were exhausted. The boys (10 and 6) easily did 3-5 hours of walking every day, and because of hot chocolate and pizza and ice cream breaks, never complained.
Nello was very gracious, proactive, considerate, and answered all my inquiries quickly and with patience. Tho he is not in Venice, he might as well be, because he knows the area, and has local contacts to provide for his guests needs. We really enjoyed staying in his flat, and won't hesitate to stay here again the next time the boys decide Venice is where we're going next.
Thanks for everything, Nello - ciao
