Mario's place is a real gem. The space is wonderful and roomy with lots of eclectic artworks adorning the walls and shelves. The whole place is clean with lovely natural light (not always the case with Venetian apartments!). The rooms were really comfortable, with an aircon unit for each one. The kitchen is small, but really functional and easy to cook small meals (the gas stove is particularly good). The bathroom is very clean and stylish. The shower is a little low in pressure, but none of found it a problem. We were a small group of four and found that it was a perfect sized place for us to stay - cosy, but with enough room to have your own space. The position is central, but not in the thick of the tourist maelstrom (it's right near the Guggenheim. which is always great to visit). We found a few beautiful local restaurants nearby. I would definitely recommend Mario's place to anyone looking for a relaxing stay in Venice.
