Location is wonderful, many nice restaurants and cafeterias nearby. Main Biennale spots (Giardini, Arsenale) just around the corner. Apartment itself is a great photo location, looks really cool, perfect for Instagram hipsters ;). Bed is okay for two. Just don't expect too much comfort: e.g., no sink in the bathroom, no curtains (you are quite visible while taking a bath and neighbor knows), no rubbish bin, kitchen is outdoors, some windows are marked with "don't open", tables are beautiful but unstable, some rusty nails, etc. We didn't meet Marie in person (communication with her was all fine), but the guy who handed over the keys to us literally ran away when we asked for towels. That was slightly strange (and a little amusing).
