1) [False advertising issue] - I did not know that we had to share vacuum, washing machine and dryer with guest in the second room, because the room was dual key apartment. Because, the apartment was designed for dual key, I did not expect I had to stay with the other guests in next door. I could not avoid hearing crazy noisy (i.e. after 11pm) from the other guest staying in the second room. - This was not accurately advertised in the Airbnb and created a false impression to me. 2) [Dirty kitchen] I found that there were uncleaned dishes, forks and knives in the washing machine, which caused a bad and yucky smells in the living room when we opened the washing machine in my second day. - I received the owner's apology and washed it before cleaner visited next date. 3) [Security Issue] Because of uncleaned dishes, forks and knives found in the washing machine, owner had arranged the cleaner next date. However, the cleaner just opened the door without knocking on the door. 4) [Bad smell in the bath room] There were terrible cigarette smells in bath room, which I had complained many times. I was afraid about smelling cigarettes is incredibly harmful to me every day I entered into bath room. 5) [Dirty room & noisy in air-conditioning] There were dust and uncleaned carpet, crazy noisy in the air-conditioning and bad smells from the air-conditioning.
