We had an incredible time. We just got back home today after a 5-day stay in Venice which was the tail end of a trip to France and other parts of Italy - we loved Venice and the apartment had a lot to do with it. This place is a very nice apartment which was perfect for our family of 4. A private bedroom for the parents and the teenagers could sleep on the sofa bed or there is an option for a portable twin cot/bed with a mattress. Two bathrooms was very nice since there were 4 of us - 1 with a tub and the other a nice sized shower.
The kitchen was well appointed for making your own meals (mostly breakfasts for our family) and the apartment had air conditioning which was a must for this time of year. The location of the apartment is truly perfect. Right between the Rialto Bridge and St Marks Square, and you have great views out the window of a canal which is a frequent route for the gondolas. We frequently heard serenading outside our window which was so cool.
As a host, Roberta was fantastic. She met us at the water taxi stop by the Rialto bridge and escorted us to the apartment, pointing out hot spots on the way, including the co-op grocery store which is a must - especially just to buy water, soda, and other food items your family might want. She ensured we knew how to operate the stove top and microwave and gave us the wi-fi password (which the kids were desparate for). She was also very responsive during our stay when we had a couple of questions or even dinner recommendations.
If you're ok with the price, I would not hesitate to book this place. We would definitely stay here again.
