Didn't know much about Subiaco until we stayed in Cameron's airbnb. From what we read, a large part of Subiaco are conserved for their history. Cameron's a beautiful vintage unit, cosily decorated with an attic.
For a family of 4, it has all the necessary amenities, very clean bathroom and toilet. The unit is located on level 2, so be prepared to lift your luggages up!
We drove, so the parking was a bit of inconvenience as it was located round the corner.
Location wise - great coffee places nearby, a park where my daughter loves to run around, good restaurants within 5 mins drive!
