Monica's place is very conveniently located, near the vaporetto station and the Rialto bridge over the Grand Canal. It is well appointed and comfortable. The air conditioning was vital in the summer. Shower was spacious and sparkling clean. Monica is an excellent host, and very responsive. She had stocked the fridge with snacks and water and milk for our arrival.
If you are not familiar with Venice, you should understand that it is something of a labyrinth and google maps is not much help. If you need to be somewhere on time, take the vaporetto (it works like the subway in NYC and you will not regret the cost of the multiday pass.) When you walk to shop, plan extra time to get lost a little (which is part of the venetian experience). We would also recommend taking the vaporetto out to Lido, and renting a bike to see the beaches.
