You can reach downtown Venice by bus within 25 minutes from Chirignago. You have busses every 20 minutes. So staying in Chirignago is perfect, if you are travelling with your own vehicle and don't want to stay in the hectic city.
The apartment is very spacious, bright, clean and stylish. The Wifi could be better (it's quite slow most of the time), but otherwise perfect. The private parking is directly below the building. Supermarkets and a fruit market are within a short walks distance. So if you want to cook yourself in the well equipped kitchen - this just works out fine. The communication and check-in was great too. So the place is highly recommended.
