I've been using AirBnB for many years across many countries and this was by far my worst experience. Details below.
Before my arrival, Hiroki asked for my flight information, government ID, and my vaccine card. I provided my flight information, my ID, and my government of Hawaii safe travels vaccine confirmation as I did not feel comfortable sharing my vaccine card with Hiroki. I had provided my Hawaii safe travels confirmation at a hotel (AIrBnB listed) stay in Maui and it was acceptable. Hiroki made it seem like a covid vaccine card was a building requirement and said "if the building didn't accept you, I cannot help you" and did not provide any further correspondence.
When I landed in Honolulu, I checked Airbnb for check-in instructions, and all that was provided was "contact the host". I messaged Hiroki letting him know I was at the building and he let me know he was at the Ala Moana, just a 10 minute lyft away but could only be there an hour or more later. Hiroki had my flight information, yet was not present at the apartment building nor did he feel it reasonable to try and get to the building as quickly as possible. At this point, I was getting nervous thinking this was fraudulent hosting as I'd never been asked for my ID ever on AirBnB nor been told my Hawaii safe travels confirmation was not acceptable during my previous 4 stays in Maui.
So I called AirBnB to try and get help with my predicament while I waited. I walked around the building and found about 20 lock boxes for self check-ins for other units in the building. Which was very surprising because when I asked Hiroki why he did not have any check-in instructions, he said "unfortunately self check-in is not available during covid...". About 15 minutes later, the building manager came up to me and asked what I was doing just hanging at the back of the building. I shared with him that I was waiting for Hiroki to let me into an AirBnB, and the first thing he asked me was why Hiroki didn't have a lock box. Secondly, I shared my name and he said he already had me confirmed for the building, and there wasn't anything else required despite Hiroki's push for my vaccine card. Another while later, I messaged Hiroki telling him that if he wasn't there in short order I would be reporting his listing as fraudulent. Only then, did he say he would show up as quickly as possible. When Hiroki arrived, instead of providing keys to the building and instructions for the unit, he once again asked for my ID information even though the building manager already confirmed me, and was still present. Hiroki then said that I can cancel the reservation if I didn't like what he was doing. Since his hosting policy is no refunds, I asked him to cancel if he felt so concerned, so I can take my money and find another place that would be more accommodating. It wasn't until the building manager literally yelled at Hiroki to either give me the keys or provide a refund, did Hiroki give me keys to the building. He also had to yell again for Hiroki to provide me with the unit keypad code. If not for the building manager, I don't think I would have been able to get into the unit - thank goodness for him. The unit itself was fine. But from a personal safety and identity theft risk perspective, I would strongly not recommend staying with Hiroki. Being prudent about covid typically means less contact not more.
