You could not ask for a better host than Hai - she needs 6 stars for communication and went above and beyond expectations!!
Pyrmont is a fabulous spot to stay in Sydney - walking distance to nearly everything: the ferry, the sea museum, the city, a Coles supermarkets, great cafes and restaurants- on the same street!
The house is lovely, with nice renovations to the kitchen and downstairs bathroom. It has everything you need there, even some Vegemite and jam in the fridge!
Be aware for elderly or very young children the stairs are a little steep!
