I stayed at "Close to Airport and CBD with Secure Parking" with Beverley and Michael for one night in July. I'd recommend the place to anyone.
Beverley checked me in. I also met Michael briefly. Note that the host instructions for finding the building are accurate, and internet map directions and looking for street address on buildings are not accurate for finding the building.
Beverley was helpful and accommodating. She has good advice about the neighborhood.
The apartment and room were as described in the listing. The photos were accurate. Everything was clean. The bed was comfortable, and I slept well. The fixtures all work, and the WiFi works well. The bedroom is quiet at night.
The complex is a five minute walk from the Mascot train station. Note that taking the bus to the airport from near the Mascot station is fast and evades the airport train fee.
The apartment is very secure. I felt no safety risk at all walking around the neighborhood day or night.
