The room that I ended up living in wasn't the room depicted in the listing. The host has several rooms under the same address which she randomly assigns to travellers without prior notice. It's blatant false advertising.
I was assigned the outermost room, which seems to be the worst room of them all. The windows are in disrepair. There is a gap between each window frame and the window sills so the hot air outside comes in unabated and the room stays warm despite air conditioning.
Worst of all, small insects can crawl into the room unhindered through the windows. After nightfall, in just a matter of an hour, my room was swarmed by roughly 30 flying ants. I messaged Anne immediately but she refused to do anything about it or give me a new room. She said this is normal in Taipei and I should just turn off the light for half an hour. What about the ants that are already inside the room and flying around? Nothing she can do about it.
Reading the comments, she is aware of the problem with her rooms for a while now but doesn't want to do anything about it. I decided to cancel my booking and thankfully, Airbnb's rep got me a full refund and reprimanded her.
Avoid this host at all costs.
