We loved Serendipity, it suited us perfectly. Brunswick Heads was very busy (school holidays) on the weekend we stayed so it was nice to be away from the crowds in the central area. That being said, it's only a 5-10 minute walk to the restaurants, shops, beautiful Brunswick River and the beach.
The studio is lovely and had all we needed. Kelly, Jim and family are great hosts. We'd happily stay here again.
