There were 9 of us staying in winter. There is only one oil heater for the entire upstairs where there are 3 bedrooms. The first night some of us couldn't sleep because we were cold, as the "doonas" provided were really bedspreads. The trundle bed was also very uncomfortable and squeaked a lot. I ended up sleeping in my parka. We had 4 elderly unwell people with us, who also were not comfortable in this house. When I rang the real estate in the morning to say that I was cold, they promised me potentially some extra blankets. However, the owner of this property responded quite rudely via sms, saying that no one else ever complained about being cold and that if we didn't like it we could find alternate accommodation!
**** Also, if you stay at this property, as well as bringing your own linen, bring doonas, toilet paper, tissues, soap, shampoo, paper towels, etc. Be also prepared to wash the floors before you leave, make up the beds, put away all the dishes and leave the place spotless for the cleaners, otherwise money will be taken from the bond! The owner's attitude is simply attrocious, that's not a way to run a business. We have never experienced such treatment in all the decades we have been travelling.
Jervis Bay is magnificent, but stay somewhere else!
