We stayed at this hotel in July-2013, and the temperature was >32 degrees everyday, so my comments regarding air conditioning is mainly relevant if you visit in the summer months. Otherwise skip the airconditioning comments.
1) Lack of air conditioning: Do NOT stay at this hotel in the summer periods or at least in the hottest part of summer. The lack of airconditioning means that it is hot and humid in the room the entire day and night and sleeping is impossible. The room is furnished with a very noisy fan, which can't be kept on the whole night due to the noise. Further more, due to the windows being opened to have any coolness, you are eaten alive by mosquitoes. None of the windows have any netting to keep mosquitoes or insects out.
2) Location is superb. It is located near the Accademia bridge, one of only 3 bridges across the Grand Canal, which allows you to explore other areas of Venice easily. San Marco's square and Rialto bridge are ~ 10mins walk from the hotel, and everything is well signed so well we didn't get lost at all. There are plenty of good restaurants and shops close to hotel too. The vaporetto stop (water bus stop) - is 2 minutes away and goes directly to the main train and bus terminal of Venice. The hotel is easy to locate if you follow the instructions they have on their website. You have to be buzzed in at the front door, rather than the conventional 'manned' door of a normal hotel.
3) Helpful and friendly staff: We found the staff to be very helpful, conversant in English and even offered a 45 min boat ride around the more unusual canals of Venice.
4) Room is basic, and rather dated but oddly the bathroom is very modern. Soap/shampoo is provided but not great quality so bring your own. Beds are firm. So apart from my comment 1 (above), the room 'does the job' so to speak. They have lifts, so no dragging luggage upstairs.
Overall, stay in this hotel but not in the summer months. If you visit Venice in the summer, find a hotel that has air conditioning.
