I stayed with Mario apartments for 2 nights in my short visit to Venice. It was a quiet place, about 15 minutes walk away from the busy tourist area of Piazzale Roma (slightly longer if you are lugging suitcases, do note there are a few little bridges you have to cross). The apartment itself was easy enough to find with Google Map. The apartment was clean and tidy, I had no issues with the water, electricity or the wifi. Mario was a great host, very accomodating to our changes in plans and very quick with responding to my questions. My friend and I had a really great stay, thank you so much Mario. =]
