I booked this house for my girlfriend and I, and it was superb. Beautifully presented, well appointed, very clean, quiet and cosy (even though it's a large house). Our host who lives nearby was very welcoming, met us on arrival to show us around, and was available if needed during our stay. It's an awesome central location: the Beaufort street strip is just a two minute walk away for drinks and dining, and Northbridge and the city centre are only 10-12 minutes by bus.
I've stayed at plenty in Perth but this was by far the best. We loved it and would definitely book again, especially for a family get together, as this house can accommodate 8 people very comfortably. Definitely recommended.
