Great apartment. We were very happy here. The apartment is owned by a hotel, but on a side street not far from Piazza San Marco. We were very happy with the apartment. The bed wasn't very comfortable--could feel springs in the mattress and one of the two showers wasn't working (but it wasn't a huge inconvenience). It was great that a person met us and took us from the Allilaguna to the apartment, since we were tired from the flight and I'm not sure we would have found the flight otherwise; he was helpful, but turned out he forgot to have us pay then for the local taxes so we had to take time out of our plans to find the hotel location on a different day and pay then. He also didn't explain how to use the appliances such as turning on the hot water heater or using the washing machine; we figured those things out, but it would have been nice if he'd explained it from the beginning since we didn't know to ask in that moment.
Overall, we were really happy with the apartment. It was VERY clean, smelled great, beautiful apartment, fabulous location, just would have been nice for those other details to be included in the overall experience.
The apartment would be perfect for a couple with two small children. It has a queen bed with a bathroom next to it in the same loft area, and then a separate little living room with a bathroom and in the loft above two twin beds that have very little room for your head between the beds and the ceiling (great for a kid, not good for an adult).
