We had a great stay at Helen's. The location is absolutely perfect - a quiet street in the middle of everything and a short bust from the city or beach. Absolutely ideal. The house is just as the pictures and has everything needed for a happy stay in Sydney. Helen is always online and available.
We stayed in the middle of a hot spell and there is no air-con so it was hot at night and the lack of an upstairs bathroom could be an issue for larger groups.
