Sorry to read these comments.
I’m sorry you didn’t enjoy the time, but I don’t agree your comments are accurate.
From the very beginning you have been hostile asking for discounts.
You asked for extra towels without wanting to pay a fee for them.
I’m surprised about your comments about cleanliness, I don’t remember you mentioned anything about it. I do have pictures from the cleaning service that proves the good state of the flat at your arrival.
About the towels, we always leave 2 pair of two towels per guest.
It’s suspicious you complaint about towels after you asked me to leave a lot of them for your stay. I gave you the option to have extra towels but you didn’t want to pay the fee. ( the cleaning service is not free for me, I have to pay for them too ).
You left the flat in very bad conditions, very dirty.
Your communication skills were also very poor as you didn’t reply my messages for weeks.
You got late to the checkin.
I don’t recommend to have Seoyoung as a guest.
