Great place with an amazing location. The only real noise was the sounds of the boats outside the window. It is that close to the canal. So, that added to the already excellent atmosphere.
It is not huge, but much bigger than most hotel rooms. There is a small kitchen with 2 burners and a refrigerator. There is not a microwave or oven, so consider that if you are planning to eat in. However, your menu should also consider that you are about 7 minutes from the Rialto Market where you can buy very fresh fish, fruits and vegetables. There is also a grocery store 1 minute away. It is a very convenient location for everything.
One of the other great things about this apartment is that it is right near Bastilica Frari. I believe this is the most beautiful church in Italy. It is worth more than one visit.
Also, if you have any problems with mosquitos (it is Venice, you probably will) use the plug ins found in the closet between the windows. They really work. Bring bug spray if you plan to be out around the canals at dusk.
