Casa Sofia has the best location, everything is close and easy to find. The vaporetto stop is a few meters from the apartment (very helpful when having heavy suitcases). Also, the traghetto (the wather bus just to cross the river) was next to the vaporetto, so if we want it to go to the other side of the river to Rialto market, it was very easy and cheap. The apartment was extra spacious with a lot of windows. The kitchen was the best, it had everything! Even some food :) The mosquitos usually love me, but there was mosquito repellent to plug-in and I didn't have any mosquito bites in all the staying here. Paolo was very helpful, he helped me when we arrived with my suitcase for 4 floors of stairs! Thank you! He gave us a map and showed us where the grocery stores and areas to eat were. Really nice staying, I will no hesitate to stay here if I go back to Venice again.
