This was my family's (wife and two small children) first trip to Venice. We were very lucky when we chose this place, it was relatively close to a water bus stop and we only had to cross up and over one canal bridge when transiting from the water bus stop to the apartment. This is very convenient when rolling your luggage and kids from the water bus.
Francesca and her husband are absolutely stellar hosts! they gave us a quick down and dirty where to go and how to get there. One of their recommendations is my family's favourite restaurant in Italy and we traveled to 5 different locations in the country.
The unit is up-to-date and amazing all of all of the appliances were in perfect working order and we never ran out of hot water the entire time which is known to happen throughout Italy.
My family fully intends to come back in the future and stay in their unit. The biggest decisions when travelling is deciding where you are going to stay. All I can say is that you will not go wrong choosing to stay in their unit.
