Marco, Monicas husband picked us up at the Piazzale Roma and showed us the way to the apartment. As we checked-in he accompanied us to the city where he recommended a great tavern (Osteria da Codroma). The apartment was very clean, the communication was excellent and you could find everything you need for. Towels, a kettle for those who like tea, a classical italian moka for delicious coffee (incl. coffee), pans, cuttlery,... There were even waching machine tabs, if you need them. The little balcony was nice to enjoy your morning coffee or a glass of tasty wine.
The apartmenrt itself is super central, you can walk everywhere and you can also take the vaporetto as there is a station close-by. There's also a small supermarket if you need anything.
I've stayed there with my sister and my parents for the Biennale and I would definitely recommend the apartment and would come back a second time when visiting venice.
