Everything was exactly as Laura described it. The apartment was spotless. The bed was very comfortable. The location was excellent, just a few steps (and 3 small bridges) from the San Stae vaporetto stop. Directions for getting to the apartment and to other places (market, etc.) were clear. Alas, street names are hit-or-miss, but you can't be lost for long in such a small area. Be adventuresome and enjoy yourself!
The only negative for me was the shower. If this is your first trip to Europe, don't expect anything similar to what you have at home in many places in the U.S. Showers in Europe are small. It simply is what it is. This is not a reflection on the apartment overall, because the shower was brand new and nicely designed.
Finally, Laura was most helpful, both during our planning phase and while we were there. We recommend this apartment most highly. If we were going to be in Venice again she would be the first person we contact.
