It was really hard to contact him, I even contacted him a week prior to when I would arrive to figure out the exact address and how to pick up the keys. However, he did not respond until I actually landed in Taipei, and had to contact Airbnb in order to get him to reply; overall making my vacation a very stressful experience. Be prepared to fiddle a couple of times with the door lock before you figure out how to do it properly. Make sure you do not accidentally lock it or the person inside will get trapped. Although he sent us a video, which was very thoughtful, but pushing and pulling on the key cannot be seen so we had to fiddle with it ourselves for a good couple minutes until we could figure it out.
In terms of cleanliness, the mop/broom had a really obnoxious smell so we had to give it a rinse and wash it before we could use it to brush the water accumulated during a shower.
The rooms were a decent size and he provided us with clean towels, utensils, flipflops and toiletries as accurately depicted in the description.
