Roberta's place was located further from the main (and noisy) touristy area, it was great for a 5 night stay. The view from the canal and having a table/chairs was also lovely.
Her place was accurate to the description/photos. A/C worked great for how hot it was outside in July. It was clean for our arrival but there was some plaster falling in the bathroom from the ceiling over the days, and the drawers below the sink were partially broken and did not close. It didn't affect our stay, and of course Venice is old, but just a note.
You can hear/see the gondolas passing by from around 8am, we kept the shades mostly closed, it was great to have two sets of curtains. It was not particularly loud but if you're looking for absolute silence and privacy then it's not the place for you.
