Poly, Petar and their beautiful daughter are wonder hosts! The family was not home when my girlfriend and I arrived, but Poly made sure we contacted her by mobile when our flight landed and she provided us with detailed directions and instructions on how to get to/enter the property.
The property is a short walk from South Yarra station and the tram literally stops just down the street from the apartment. The room was simple, comfortable, tidy and exactly what we needed after a day of touring Melbourne.
Although we didn't see the family much during our stay, the small interactions we had were always pleasant. Poly really made us feel at home -- she basically offered us everything in the refrigerator and pantry. We didn't feel like we were staying at an AirBnB but more like with our Melbourne family :)
Best of luck with everything Poly and Petar! Thank you again for being such great hosts!
