Either there was a miscommunication or the host simply wasn't available; I am not sure. But I contacted the host 48 hours prior my arrival day to make sure the apartment I booked wasn't cancelled and I didn't hear anything back for at least 32 hours. I was so desperate and didn't want to become homeless upon my arrival, so I contacted AirBnB customer service for help (they were amazing and super helpful). AirBnB tried to reach out to the host, but still unable to reach the host. Finally, around 10:00PM the day before my check-in the host finally replied. At that point, AirBnB was already assumed that the host simply wasn't available so they refund my money and cancelled my reservation and provide me the option to re-book with other host.
Long story short, I ended up re-booked the apartment with host Kumiko; she was simply amazing and the replace was awesome. Highly recommended host Kumiko when you are looking for a place in Taipei.
