Kate, really sorry for your troubles, as you know we had issues with changing your arrival date because originally you booked for the 1st, but later tried to change it to the 2nd of Jan, and airbnb did not allow the change because the length of stay fell under minimum. This is all automated on airbnb.
So I changed the minimum, but by then we were already into your original date of arrival. Plus I was away for New Year, so I couldn't respond to emails right away, because I was travelling, and so were you.
As you arrived at the house next day, I refunded you one night stay.
We had talked about the safety factor, and I assured you that many women travellers have stayed in the house alone, as I do as well. (you can read several great reviews from women travellers). Not sure why you felt worrisome on your own. There certainly was no reason for these worries.
As the house is situated in the rice fields, we live with all manner of critters that populate the fields. They don't come into the house unless there is food left lying around, so perhaps that's what happened.
As for mosquitos - it's true that they multiply in the rainy season, that's why we have a mosquito net over the bed that can be tucked in snugly, so no mozzies can sneak in. Perhaps it wasn't secured and they got in.
