Really nice location in Cottesloe very close to beach. House itself is comfortable and has all the things you need. Like in most houses in Perth the insulation was not what you are used to in Europe: when we were there in August it became really cold inside the house and the infrared heater couldn't help to overcome this coldness.
Regarding privacy: the house is in the backyard of the hosts house and the curtains are not fully blinding off, so you can have the feeling that you have no 100% privacy. This was for us not a uge deal, but perhaps good to take into account. The host was very friendly and was even giving excuses that she didn't had done so much groceries to have to fridge filled with stuff.
All in all a good place to stay!
