We spent the weekend with our children in Venice and this apartment was perfect for us. Great location for travelling with little kids (1y & 3y) for several reasons:
1) Waterbus station is very close by and the apartment is easy to reach - only one bridge (if you bring a stroller)
2) There is a big square right in front of the entrance so the kids can run around a bit without problems
3) Supermarket is right around the corner
4) Bars for coffee for the parents and ice cream shop at the square, restaurants and food to go 2 min away
5) not even 10 min walking distance to either St. Marks Square or Rialto Bridge
Also, everything was explained very well by Chiara (we arrived at 2:30 am!!!) and we had no trouble finding the place and checkin-in.
You will be very happy at this apartment!
