Allan & Joan's place is great. It's a great hub if you're looking to do day trips up to the Pinnacles, Yanchep etc and is a short drive down to Perth, Freo, Rockingham etc. It's close to quite a few bars and restaurants (walkable) and the main shopping mall (also walkable, but much better if you have a car).
The flat itself is clean and has everything you need (including washer and dryer for those staying longer) and hidden touches such as 'emergency groceries' were very welcome indeed to help us settle in. The bed is super comfy and there are plenty of power points if you're all tech'd up.
Couldn't have asked for more for the price and Allan & Joan are really friendly. They'll leave you to your own devices if you need some quiet time but we're always very chatty when we bumped into them.
Highly recommended.
