The apartment is in a great location a few mins from St Marc square in a posh shopping area. Easy to get to using the Vaporetto. We traveled with our 5 month old son and the apartment was almost ideal for us. Comfortable , clean and spacious - pretty much as described. We didn't need a cot but one was provided when we arrived which was nice. The only real issue for us was the shower. A very small cubicle with water temperature that kept going up and down every couple of minutes. Not fun. We also had an issue with the heating in the apartment which left us very cold on the first night but this was rectified the next day by Corinne.
Overall we had a great stay and would recommend.
