I stayed in this place by myself. I had great communication with the owner prior to arrival, she responded really quickly to any questions and allowed me to take a look before confirming the booking. The place is lovely! It's small but really well equipped and makes great use of the space. The owner also offered to remove anything you don't need to so if you are a couple you can have more space.
The kitchen is well stocked in terms of utensils etc, the bed is comfortable and generally feels quite modern but simple. It still retains its privacy set well behind the main house and with a nice garden around the block. The street generally is low-key and quiet (in a good way).
The studio is about 10 minutes walk to a major bus stop (and Warringah Mall) and about the same to Curl Curl Beach. I would recommend it and will stay there again.
