the host will call the guest 24 hrs before to check weather you have good reviews .. and then later, the host was informed that there is going to be a late check-in .. because I was traveling with 25 day old infant .. I was not allowed to check in without paying some extra money ... the host controls the doors keypads from his app manually. door handles were already shaky ... when you call the host that the code doesn't work they will blame you for that condition... not at all recommended
