This Airbnb is in fact an agency, not a host. It matters in that it changes the booking system and check-in system and makes it very difficult and complicated to suit themselves and not the guests.
I prefer to book a real local host Airbnb, not an agency on Airbnb. If i were to book an agency i would do their site, not Airbnb. Due to their extra, doubled up and extensive check-in and booking requirements, I requested a booking cancellation or change of date.
My email queries to them about cancellation were ignored until past cancellation period. Then my date-change requested was rejected with no grounds for it. All the while their emails stated my booking was not confirmed, although it was confirmed on Airbnb.
Contacts about my check-in were only done after date-change was requested and not for actual help but to cover-up charging the booking for no reason. This outfit is out for profiteering off guests, not to provide a service or to host guests.
