My friend and Istayed here for two nights and this place was great! It is exactly as pictured and you are right on a canal and I really enjoyed putting my feet up and watching all the boats go past. The whole place feels very traditional and Venetian and with the windows open there is so much light in the main living area.
Mario is an excellent host and even came and found us when we got lost! He made sure we got our bearings before he left us and recommened some places to eat :)
It was very easy to get to and from the apartment when you knew which direction you had to go in. Two handy tips for anyone travelling to Venice: bye a good map and you will be picking up your luggage constantly to go over all the canals bridges...pack light!
If I ever get the chance to go back to Venice I will definitely be staying here again :)
