Maria's unit is right across the canal from the S. Lucia train station and very easy to get to. Highly recommend this place so that you are not lugging suitcases all around Venice. Check-in was smooth once we found the correct alley, and Maria got us settled into the unit. She has a nice AC unit that you can control with a remote that was great for the humid summer, and a mini-fridge to store drinks/food.
For any guests who are considering this AirBnB as a stay before a cruise, this is the perfect unit. You'll be a quick walk away from the people mover tram, and Maria can hold your suitcase in her primary apartment on the checkout day so you can explore before boarding the boat.
For daily exploration, we were able to walk to Rialto bridge in around 15 minutes and had very close access to the vaporetto station. Nearby there is a laundromat and I highly recommend the G. cafe for Gelato/lunch.
Overall the bed was comfortable, large and firm. Outlets behind the bed for charging devices. Just make sure to use insect repellent of some kind in the summer so no mosquitos attack you in your sleep :)
