They want to cancel after the check in
Two guests arrived today, and when entered the apartment they said that they didn't like the area where it is located and that the house has "negative energy". Its the first time that i come across something like this and all of my previous reviews are above 9,5/10. They asked me to return the money they paid, but i have already paid for the cleaning, and the lady that hands over the keys. What should i do ? If i keep my policy and do not return the money back, will they still be able to leave a review ?
Thank you for your time Kimon
