Ludovica's apartment was just delightful. The location could not be beat, with proximity to multiple vaporetto stops and just a 10-15 min. walk to Piazza San Marco. There are ample shops nearby, including a supermarket, bakery, and gelato shop. It is also close to a garden area which is just delightful. The area is lively during the day, but really quiets down in the evening was not a problem for sleeping.
Ludovica also kindly met us at the vaporetto from the train station, and was able to answer all of our questions. She was also available to answer some questions throughout our stay.
The space serves was sufficient, but it's also worth noting that two of the bedrooms are attached, and one only has a curtain for a door, which did limit privacy somewhat. Overall, however, highly recommend.
