The apartment is located in the heart of Venice. It is walkable to all tourist attractions. Not really walkable from the train station if you have luggage, you should take a water bus. The apartment itself has a fantastic view of the Grand Canal, which is a major reason for our stay. The rooms are clean, and bathroom is also very clean. There is a fish market downstairs, which is convenient for us to buy seafood and cook in the apartment. The market gets noisy in the morning so it's good for early-risers.
We had one issue - there was quite a few mosquitos in the bedroom (mid of Oct) and we had mosquito bites. Closing the windows might help. Overall it was a good experience.
