Just stayed here for two days with my husband, and loved it. We had the canal view suite, and it was even nicer than I hoped. The suite is in the building next door, with it's own front door. There is a spacious entrance hall and a gorgeous (massive) bedroom with sofa and small table and chairs. The bed is large and quite firm. We both had some great sleep here. The bathroom is great. Modern jacuzzi bath with a tap in the middle (why aren't all baths like that?!) and wooden headrests at each end, two sinks, and a massive rain shower with jets.
Breakfast is continental, and can be served in the suite. The staff are all very friendly and accommodating. We were made to feel very welcome.
There is a water bus stop very close to the hotel. This is on the airport route and makes transfers very convenient. It is not on the Grand Canal route, but its really easy to either transfer boat onto that route, or walk a few minutes to a stop that is. We managed to walk to the San Marco area in a brisk, but pleasant 25 minutes.
I would definitely stay here again if we revisit Venice.
