I have stayed in Buenos Aires many times, using Air BNB. I have always been pleased with the communications. Mai is not involved in the operations of her apartment. Monica is the person responsible for dealing with the customers. Our flight arrived very early in the morning so I rented the apartment a day early to have early access. I asked Monica to give the key to my brother-in-law the day before check in. She did not meet my brother-in-law but instead left the key with the porter. For check out, she asked us to leave the key in the apartment. I never met Monica. When we first arrived, we had trouble with the remote control for the television. After changing the batteries, we told Monica of the problem. She said she might be able to replace it but probably not. We never heard from her again and we were there 34 days. Also, on check in, there was less than a quarter roll of toilet paper. When I asked, they said it could be purchased. Monica never checked on us.
