I have a guest that stayed from Fri-Mon. I checked them in myself, went over the apartment with them and made sure they were OK. Told them to contact me at any time if anything weren't OK or they had any questions. Sunday they contact me because the apartment was a bit cold. I went over with firewood enough for their last day. All good.
After they left, in which they just left the key in the mailbox, which was not agreed upon, I got a long letter in which they told me they were not satisfied with their stay. Mostly because they felt it was dirty (which it was not). They sent me 12 pictures, most of which just showed usage and not actual dust. Yes, there were some dust which could have been fixed.
My problem is, they are claiming over 50% refund because of this. Not once, not even when I brought firewood, was I notified of any problems. I would have gladly fixed this for them if they had let me know, but only after they left did they tell me anything. The pictures was sent monday after they left. Am I completely in the wrong here, or is this claim a bit ludicrous?
