Hello,
my guests stayed at my apartment for a little over 2 months. I just received my water bill and it was 10x what is normally used here. Also, they purchased an air conditioner and my electricity bill is 6x the norm. I have the paperwork to prove normal usage vs theirs but I am not sure what can be done since nothing about extra costs was listed. I have been using AirBnB for years and this is a first. The total for water and electricity bill will come out to be about month's rent. What can I do?
