I'm very sad to read this review. I wish you had communicated this before, so we could have handled it. Apparently something went wrong with the cleaning lady? One call and we could have send her immediately.
I take this as a lesson, to double check that the house is really clean on the day of arrival. (When we are away, our friend and neighbor helps with check-in, so I will ask him to check the house again to make sure we prevent this from happening in the future).
But mind you, this is Thailand and living semi-outdoors means that nobody can guarentee a 100% insect free place ;)
We love our little house with it's amazing view and relaxed atmosphere. We genuinely hope others will also - as they have so far!
