I am very sorry, I absolutely did not want to violate your privacy!
Let me explain a few things:
I am a big fan of airbnb, for me it was the first time renting out my apartment and I was a bit nervous because of my belongings.
My girlfriend who gave you the keys and who is living next door told me that she saw another person in the flat when she walked by.
You rented my place explicitly for one person, dear Manuel!
The next day when I finished work I decided to introduce myself and say hello to check if you have any requirements.
I rang the doorbell a couple of times and knocked on the door.
Noone was answering but I saw another person standing at the window when I walked by. So I went in to check that everything is okay.
I should not have done so, I am sorry for that, but as I said it was the first time renting out the apartment and I was worried.
Your son (?) opened the door, we spoke a few words, he was friendly.
You should have told me in the beginning that your son is planning to stay with you in the apartment. Than everything would have been fine and ok for me!!
And just to let you know: I used to work and live in a hotel..I absolutely do not understand your concerns and I am quite disappointed about your comment.
But I am trying my best to improve. I hope that you try to understand me, wish you all the best.
