Before replying to you, I would encourage everyone to look at all my guests' reviews; in particular, the review of the guest who check out just before you and the guest who arrived the same day you left. And ALL other guests. Everyone raves about the cleanness of my flat. I really think your review is not fair and I am sad your review is not an accurate representation of what actually happened. But I am glad everything is documented on Airbnb regarding this case.
You raised an issue with cleanness 5 days after arrival!! which was unreasonable as it was impossible to check this after you stayed in the flat for 5 days.
Regarding the "mould" I am very surprised about your comments because you told me that after a closer look you realised that it was not mould and you decided to stay, although I did not mind if you left as I told you.
The reason I offered 50 Euro was not for any inconvenience but for the "misunderstanding" and only as a gesture of good will to clear up the air after all your complaints. I knew being of Airbnb community we may meet again one way or another and I wanted a good relationship. Although I was the one who felt the unfairness, with complaints that were impossible to check and a guest who keeps changing their mind and will not be happy no matter what you tried to do. Unfortunately the payment and my gesture of good will was "misunderstood" for a refund for "inconvenience" but I would do it again and I do not regret treating my guest with the highest respect no matter what!
