The house itself has been beautifully renovated and is a comfortable space for 2 families. Be aware that Maroubra Road is a main road which can be quite busy but you don't notice the traffic noise inside. It was very easy to get around and there is plenty of roadside parking.
There were some basic housekeeping issues: sheets not clean for the sofa beds, air mattress had holes and the BBQ was filthy. Breakfast is not actually provided, it was a half used box of Wheetbix so be sure to take your own.
The biggest problem was the lack of communication. We emailed and texted Hai multiple times before and during our trip and had no response.
