Marco is super responsive and worked with us to make finding him for check-in an easy process. Venice is easy to get lost in, but he guided us to the location and pointed out some local spots to help us orient ourselves and purchase groceries and the like.
The location is fantastic. You are very close to the Rialto Bridge and Market and an easy walk to St. Mark's Square or the Cannaregio district (where our friends were staying). And very close, if not a little confusing, to the Vaporetto stop, which is an easy way to navigate the city and get to the train station.
The back of the property is on a canal, so workers and gondolas would go by occasionally and the windows opened to hear the water and the sounds of people wandering (likely getting lost) in the city. The two bathrooms were nice and it had AC (though we didn't need it.
Only 1 key was provided, which made it a bit tricky when I went to the market while my travel companion was showering. I returned to find the place dark (key card needed to use the lights) and hearing him ask what was going on. Comical experience for me though.
