We went for a girls weekend, there was eight of us. The Shack was very comfortable and much bigger inside than it appears. The kitchen has great working space with plenty of dishes, platters etc.
Backyard is very secure with table, seats and large BBQ.
It is within walking distance to the beach but a car is required if you prefer to drive the 5km's to Port Lonsdale or Queenscliff. Side note: Do no rely on Taxi's, or Ubers, make sure you pre-book well in advance. As l live on the Sorrento side l decided to catch the Ferry without the car.
Overall we had a fantastic weekend and stay.
