Visited Istituto Canossiano early, last summer, with a group of 20 or so, adult students. Rooms were spacious and clean and adequately appointed. Communal kitchenette served our group well, especially those who chose to shop and prepare food in house. Courtyard was lovely and quiet. Dorsoduro location was convenient to vapporetto, shopping, cafes, restaurants, museums, churches, all that Venice offers.
