Mt Lawley is another good area, close to the city, nightlife, eateries etc.
IMHO, your best option is to pop over for a quick look around, and visit some of the suburbs. The area's closer to the city tend to have older houses and are more expensive, some of the suburbs further out are newer, bigger houses etc.
Give us some idea of what your work will be, and we may be able to provide better advice.
