Apartment is very convenient, and located in San Marco district a few minutes walk to San Marco Square.
Kitchen is well stocked; Jack & Jill bathroom (shared/connecting shower), clothes washer available (dryer was out of order during our stay), but clothes line available on window ledge; majority of the windows look down on small canals!; great Venice books for trip planning; no elevator, be prepared to haul your luggage up 2 flights of stairs.
Tips:
1) Take water bus 2 to Rialto, and definitely pay a porter to help your party with luggage if you're not comfortable managing all of it through crowds in narrow alleys, and up/ down the small bridges' steps to the apartment. (Note: porters not always available to help you leave the apartment...)
2) If coming during fall/winter, bring waterproof shoes or boots, as the courtyard of the building floods due to it's location in the oldest historic area of Venice. (San Marco area is prone to flooding during high tides)
Luciana was a great host, and met us at the water bus stop. She gave us great advice about sights and food. She even brought her nephew to help us with our luggage down the flight of stairs after 1 of us hurt their leg.
We spent a lot of time and had a very nice stay in the apartment. (We were forced to stay in the apartment for an entire day during the epic Nov 2018 flooding, 156 cm!)
