This was officially my worst Airbnb experience. And it was mostly because of the host's racist and inappropriately rude behavior. The place was not cleaned well and there was dust everywhere, especially in the corners of the sofa bed and the rooms. Even the carpets were filthy and I had to wash them myself in the washing machine. In the end, I left everything in a much better condition, however, she blamed it that it was not "clean". As if I was expected to mop and leave shinny floors even though a big cleaning fee was charged. She kept changing her mind regarding the Anmeldung and took our communication off of Airbnb for some time which was a very bad experience. She changed her mind about doing Anmeldung almost 9 times and suggested to make a rental contract for 2-3 more months. I am so happy that I gave up with her and found someplace else otherwise she would have made my life worse. I stopped replying to her or and taking her calls unless the messages were from Airbnb chat. Her freezer's door was broken and also the part where the shower head is kept was almost broken and I had to manage it somehow for 1 month. Even when I asked her to change it, she didn't. The place is very old and you'll be welcomed with dust if you open any of the cupboards. The bed was also very old and not comfortable for a long stay. The hot water would come very slowly due to an older heating system. Some of the neighbors were also very loud during the evening and night time so that caused a disruption of sleep. The room window is also next to the trash collection spot of the apartment and so during the night your sleep will also be disturbed when the trash collectors come for trash collection between 3-6 AM. The location was quite good and her husband Tien who welcomed me at the Check-in was a great guy. But Wendy is the troublemaker and a super racist person in her remarks and actions both in person and while on call. I'd highly suggest not staying with her due to her unwelcome nature but if you do, keep ALL communication on Airbnb chat so you can report her. Also, her English is very bad and takes a long time to reply. So it's best to talk via Airbnb. Overall, I'd not recommend a stay with her or her place especially for longer stays. Due to her illogical and untrustworthy nature your stay can really be ruined by her negative behavior so it's best to find some other option during your stay in Berlin!
