We stayed a few nights as 4 people.
Location: Really lovely and quiet neighbourhood with a few handy stores nearby like pharmacy, book store and a supermarket. The bus stop that'll take you to Venice is a couple of minutes away (walking distance) and there's a local market every saturday morning.
Flat: Clean and it has necessary appliances are available for use as posted: washing machine, dryer, microwave, there's traditional gas stove, no dishwasher. There's a TV in the dining/living room and one in main bedroom. There's only one AC unit. The bedrooms can get warm when doors are shut so having the doors open is an option to make rooms cool. Internet connection was good.
Check-in: It was self-checkin but we were provided booklet that have necessary info about supermarkets, wifi password, public transport, cafes/restaurants. Communication with host was good before and during our stay. Host was responsive for questions.
Just to note you will have to pay for City Tax, it's separate from booking price. Overall we'd love to stay here again.
