I have stayed at the Locanda Sturion (it is in Karen Brown's book on Italy Inns and Itineraries) - it was right near the Rialto Bridge - very lovely. Just note that there are many stairs to get to the hotel and no elevator - so if stairs are a problem this place would not be good. It was about $250 Canadian per night. The breakfast was great and you sat in a room overlooking the canal.
