This house was great for our family which included 2 toddlers and a dog, as well as two seniors. The main floor is open and has gorgeous windows with a view, plus a gated deck to expand the living area. All the bedrooms are on the lower floor, which works perfectly. this house worked really well for us, and we would probably stay here again (unless we can find one with an easier beach access). Avon itself has good restaurants, and the pier is a fun activity. There are playgrounds for the littles. It was a good location.
Some things to note:
The walk over the dune to the beach is challenging for seniors.
There are almost no supplies provided in the house. You will need to bring (or shop on check in night) dish soap, dishwasher soap, paper towels, laundry soap, cooking needs (oil, spices, etc).
