Marco was fantastic. He was very responsive, nice, and easy to talk to. While we didn't meet Marco until check out, his friend that checked us in and met us at the boat stop was equally as friendly.
The location is great, on a fantastic street full of locals and great restaurants. Also, drinking a bottle of wine on the roof deck of the apartment is a must try! My only advice would be that the apartment has a washer, but no dryer or obvious drying lines, so don't plan on doing laundry if you're used to a dryer. Otherwise, its a perfect spot to explore Venice from!
