Although Beverly and Michael are not originally from Australia, they are very knowledgeable about the area of Sydney they live in (Mascot) and major tourist attractions in the city. From our experience, they enjoy long chats about any and everything, which can be quite pleasant if you like an engaging set of hosts.
The apartment block is only about two and a half blocks off of the T8 train line, which goes directly to and from the airport if you are not renting a vehicle. If you are renting a vehicle, like we did, they have a dedicated parking space in the garage under their apartment complex which is accessible with the same key fob you use for access to the premises/elevators/etc.
The complex the apartment is located in is rather large, so do make sure to ask for clarification insofar as how to enter from and exit to the correct street when traversing the area. They are in the B building, which is the furthest away from the Church Ave entrance of their block, but very close to the Gardeners Road entrance. It is a gated community with very well marked buildings.
Of course, Beverly and Michael provided us with towels, shampoo, soap, and all the other basic travel accoutrements one would expect to see upon arrival. We used their washer and dryer while we were at their apartment, and Beverly was very helpful in showing us how to use their unit (and Michael, too, when we forgot how to adjust something during our second load!)
Over all, if you like a more private stay when traveling, this won't be the place for you, but if you enjoy having someone to have tea with in the morning and to chat about your day when you return at night with suggestions and ideas for the following day, Beverly and Michael are your best bet!
