it was lovely having you stay and thank you for leaving the house so clean.
I am sorry to hear you felt cold, I forgot to mention that the ceiling fan in the lounge room moves warm air down and into the bedrooms. I have never needed extra heating while I have lived there. Although I did grow up in Victorian weather. I assume you found the extra doonas in each room.
All the best for the rest of your holiday,
The external doors are fitted with deadlocks (normally the case in Australia). The latch can be pushed in so you can go outside without needing a key. Just a small thing that may help for any further stays.
