As other reviewers have mentioned, Nicole has really put in a lot of effort and care to the place. The fridge (Wine, Orange Juice, Yoghurt, Fruit etc) and the flat (Buses, maps, info) is stocked well above our expectations. The flat is as advertised. I'm amazed she's not a Superhost yet. She'll get there no doubt.
The flat is not very far from Warringah Mall or Manly Beach. We didn't have a car but we didn't find it too inconvenient catching buses around (assuming you don't mind a 12 minute walk to the main road with a hill). An Uber to either of those 2 places will cost around 14 AUD. There's also a special bus that goes to Warringah Mall 5-6 times a day close to the place. The bus to Manly was about 20 minutes. Even the CBD (Wynyard) was only 30 minutes if you take the B-1 express buses.
The things to note are the bed is a bit higher than your average bed.
Also, you might hear footsteps above every now and then, but the Host family was mindful enough to keep it to a minimum. It didn't bother us to be fair.
I manage to get some work done I was here and can report the Internet speeds were faster than some coworking spaces I've been to in Australia.
I would heartily recommend this place if you're planning to explore the Northen Beaches or the CBD
