Alex has been an impeccable host to me. He had no problem checking me in at 2 am due to my late flight, answered all my questions about the surrounding area and australian customs. He shared his culinary recommendations with me which have been incredibyl helpful in finding perfect spots for lunch and evening beers. When I had a problem with my australian sim card he lent me his phone to help resolve them.
I wholeheartedly reccomend staying at Alex's place if you find yourself travelling to Perth!
