We stayed in Antonio's airbnb as three English undergraduate students, studying in Venice for a term with our university department.
While the apartment appears slightly larger from the photos in the listing, there was certainly enough space for three to live comfortably (two in the main bedroom and one in the smaller, side bedroom). The kitchen was very well equipped and had everything we needed to cook daily meals with, and it features a full-sized fridge which is undeniably very useful. The sitting room was also fab (and is a space which many of our peers' apartments didn't have) and has nice comfortable seating for watching TV, or for having gatherings of more people. Two bathrooms is also a rare feature for an apartment of this size, and makes life a whole lot easier so I cannot recommend that enough. The washing machine and clothes line in the downstairs utility room were also super helpful.
Overall was a very good, comfortable stay, and i cannot recommend the apartment, or Antonio, enough! :)
