BAIT AND SWITCH!
4 problems: 1) the check-in procedure said lockbox, but the host wanted to meet in person. 2) the address the host wanted to meet at and rent to me was not the address in the listing. 3) the host had no pictures or Airbnb listing for the alternate property. 4) the check-in procedure was supposed to be emailed to me 3 days prior to my arrival. The host didn't send it to me until 3 hours before my arrival... I was boarding my plane!
Needless to say, I contacted Airbnb, complained, and then canceled this booking for a full refund.
I think this host is double-booking and using a second (non-Airbnb) property to avoid having 2 properties listed.
I do not recommend this property or this host.
