We absolutely loved the apartment. The staff was SUUPER NICE. There are plenty of GREAT restaurants nearby, as well as main attractions like the Piazza San Marco, Rialto bridge and others. At times I felt so comfortable that I just wanted to stay in the apartment instead of exploring the town. It is super quiet in the evening. Basically, if we ever go back to Venice I will stay here again. The ONLY minor issues is that there were no elevators or "nice" views from our apartment, but that didnt bother us. Other than that SUPER highly recommended!
Tips: Please make sure you read the check-in instructions, the receptionist is there until around 2pm, which for us was not an issue because we arrived around noon, and they let us check in ahead of time which was great. We arrived from Milan by train, and took the water taxi right outside of the train station which cost us $90 euros. The water taxi dropped us right in front of the apartment entrance.
However, if you want to save some money, take the vaporetto (public boat) to the Realto station outside of the train station. Once you arrive at the Rialto stop, it is about a 10 minute easy walk. Google Maps will take you there, I honestly wish I would have done that (they provided GREAT INSTRUCTIONS). If you take the vaporetto, you need to go through 2 small bridges with stairs before you get to the apartment, but they are not that bad. I think the vaporetto from the train station to the Rialto bridge is about $9 euros per person.
