Christiano`s apartment is perfectly located - both at a short walking distance from San Marco square and away from its crowds, and located just in the middle of two Vaporetto stops. The neighborhood is still quite central one - vivid during the day and providing cozy spots for a drink or food in the evening.
The apartment is not big but contains everything you would need, even for a longer stay. It is really charming, including the little staircase you should climb up to it. But does this even count after completing 10 + km per day around this beauty Venice. :)
