We would like to thank Jan (and Tim) for the lovely 26 days we had in her apartment.
It is located next to a small Shopping Centre what gave us a lot of convenience for our staying with two children.
The apartment is very new, clean and fully equipped. It's only 15 to 20 minutes walking from Dee Why beach and it has a great view from the sea (much better than the Airbnb photos can tell).
At the beginning we used public transportation that is great (and expensive) in Sydney. You can take the buses only 2 blocks from the apartment.

We have absolutely nothing to complain about. The apartment is perfect for families with 2 or 3 kids.
