Future guests, I realized from my last experience when you travel to LA, expect to pay 200-300 min to get a clean, comfy and decent place to stay. Otherwise, you may just get "what you paid for": the place is not comfortable or clean enough. The location is also somewhat shaky, bordering with a shabby neighborhood nearby. Certainly not the best part in Korean Town.
Due to a super-unpleasant sanitation concern in my room, the host offered me an one-night refund when I reported the problem. After that I had to repeatedly inquire and urge him to refund me as promised, and it took my "final resort" threatening to contact the airbnb if he didn't do this immediately, before he finally refunded me through airbnb. This experience alone certainly exacerbated my initially tarnished impression about the entire place. I would appreciate it more if the host had refunded me promptly without having me go after him like a "debt collector".
