I am very sorry that you felt that way, considering that we had someone to come prior to your arrival, and that confirmed the place was cleaned, such as the sheets and the towels. We will make sure to have someone different to come and clean the place for our next host, as I would not like to have the same issues for a next traveller.
Regarding the bathroom, i did carefully look for it, and could not find more than 3 ants since our return. I would still like to apologise, this is the first time in 7 years living in this place that we are facing this, but this has been taking care of.
I sincerely do hope this hasn't prevent you from enjoying your stay.
