First time Air N B users, we travel to Sydney at least twice a year for family visit..
The good: very clean, tidy , comfortable beds, clean laundry and amenities
The not so good: to be honest bedrooms are in a loft, the air conditioner in Queen room broke down on day 1, in the midst of one of the hottest days in Western suburbs, only air was a 4" gap in window and osculating fan and was not fixed for our 3 day stay.
Double room had a portable air conditioner, again with 4" window opening that coped reasonably well with the heat upstairs.
Don't know if I would go Air N B again as far as value for money and comfort
