Overall, I would say that the host was very unaccommodating and did various things that constantly put me under stress.
I had booked the apartment for one night but then I had accidentally canceled the booking (I take full responsibility for this mistake). Since I had barely gotten any refund (I was only refunded the service charge), I requested the host to let me stay since the money had already been paid. The host told me that he would allow me to stay as long as I paid an insurance deposit (since Airbnb could no longer provide them insurance for damages). I agreed to pay this as I understood. The host then gave me his whatsapp number and urged me to chat with him there (I wasn't aware that this was a violation of the guidelines). After I messaged him, I received a message from a completely different number (it seemed to be some random lady) and she claimed to be the host, which was quite confusing to me. There, she asked me to pay the deposit through bank tranfer. After contacting airbnb, they advised me not to do so and suggested that I ask the host to request a payment through airbnb instead. After I brought this up with the host, she threatened to refuse me staying. Because of this, I decided to book the room again as the host agreed to refund me on my second payment (excluding service and cleaning fee). Even though she knew I was a student who was hesitant about paying so much, she decided to take advantage of my situation. Before I could book the room again, she increased the service fee by around 1000 hkd! So I ended up paying even more.
Another thing was that the host provided the wrong address on the listing. When I was about to arrive, I contacted the host for the check-in procedure. Right at the last minute, the host gave me the actual address of the apartment which caused a lot of stress and logistical problems since there were a lot of others coming too.
Lastly, in the middle of my stay, the host sent someone to the apartment to collect a lamp and I wasn't informed about this. the person who came to my door just entered the room and was about to take the lamp until I stopped her. I was scared because I didn't know who she was and knew that I would be liable for anything that is stolen. It was only later that the host informed me about her. Such an encounter shouldn't even happen when guests are occupying an airbnb room.
My whole experience with this host was unpleasant and it felt like they were constantly trying to take advantage of me.
