The check in instructions require a 2 step verification outside of the Airbnb app. For travellers like myself who are either on wifi to avoid roaming charges, or who purchase a local SIM card, we cannot use their 2 step cerification because it only sends an SMS to your original SIM. Their customer support was super slow to respond and completely unhelpful. I repeatedly asked if I could send the required info by email but no response. I couldn't get the check in instructions so needed to find a new place and cancelled this booking. The location seemed great but no clue if it's actually a good place to stay.
