I wasn't at Poly and Peter's place for much time, as I was in town for the Australian Open tennis. Though when I was there, they were the best. They make you feel at home quickly with their natural hospitality. They'll give you access to whatever you need and let you use their appliances (though I must say I did not). They'll provide you with a public transport card if you need it - very nice and thoughtful of them. Bottom line, If you're worried about your potential host, you certainly needn't be with these two.
Location is at a nice spot, a walk outside the city center, there's also public transportation right nearby. Perfect if you're heading to the Australian Open or Rod Laver Arena area. Also great if you're looking for somewhere nice just outside the city center.
I unfortunately can't write a lot, because I spent so little time actually at their place, but I can say for sure that you will enjoy your time at Poly and Peter's!
Thanks again for the stay!
