Two extremely frustrating experiences with this host:
1. I booked a multi-nights stay at the location. The host failed to inform me on time about the passcode for the access of the key to the building, until I called them late night around 1:30am, and they blamed on me for calling them at the night. This made me wait outside the building for about 30mins upon arrival. Normally, other hosts would notify me about the information of the access of the building immediately after the booking is confirmed.
2. The room had very strong odor, which was confirmed by the other tenant (I have video recordings as a proof). The odor problem stayed through the whole night, even that two large windows were completely open. As a result, I didn't sleep well and the odor triggered my asthmatic reaction and caused short breath and tightened chest. The symptom persisted for about a week after this incidence... a nightmare. After I complained, the host only came to investigate around the noon the second day. After the investigation, they failed to provide me a room change. Even worse, they completely denied the odor problem. I asked for a full refund, they again refused and charged me for Day 1 and Day 2, only willing to cancel the remaining nights starting from Day 3.
I have been using airbnb for about 8 years and had never experienced an awful experience like this before. The host was very inconsiderate to the well-being of the tenant. I felt that myself was abused and mistreated.
