Great, central location, really exciting to be overlooking a canal, clean, bright and spacious also. Central also means that it can be loud in the evening/morning if you want to leave the window open in the main bedroom. Just be aware of it - we didn't mind and enjoyed being able to just get back for a refill during the day. The inner bedroom is quiet, overlooking a space just between other houses.
Tips: You might want to use the electric mosquito trap found in the apartment, there are quite a few of these little beasts - I guess that comes with the lots of water around. Also the owner has very strict check in and check out rules - we found a luggage store very near Rialto Bridge that was very helpful and is 5 min walk from the apartment unlike the train station that is more of a project if you just want to collect your luggage.
