Check-in was okay, we had to notify the host in order to do the check-in, so it's not great if you are arriving late because we needed to coordinate our arrival time with them. We also had to make our beds because the sheets were on top of the bed.
The biggest issue was the cleaning of the apartment. Even though the place was nice; it was dusty and dirty in some areas. When I reported the problem to the host, he didn't offer any solution and said it was normal in Santiago because of the smog. His answer was disappointing. I also didn't appreciate receiving many messages from the host to my phone number instead of using the Airbnb app only. There was also an issue with the alarm, and we had to go back to the apartment to open the door to the host and technician.
I recommend that hosts hire a cleaning service and have a backup key for maintenance issues, so they don't have to ask the guest for support.
