Staying with Poly and Peter was so nice! They are very carying and open to help you with all your needs. Poly even offered to pick me up at the airport which has been a real pleasure after a long flight.
The flat is very good located. There is a tram stop right down the street, the city of South Yarra is very close and you have the choice of various beautiful parks nearby. By tram you are in CBD in about 10 minutes.
I recommend a stay with Poly and Peter and would come back every time.
