Though the company/listing says their will be a greeter to allow you inside, the greeter is actually a person from the company NOT the building so talking to the building concerige doesn't help.
When we arrived even after several emails to the company they kept telling me there is a greeter to allow us into the room, made phones calls and they were giving me the same thing, after looking around online the company is not based out of Washington and they have a 'local" team that allows their airbnb renters in, NOT the greeter that is supposedly there.
After SEVERAL phone calls and emails waiting for 2 hours someone arrived to allow us into the unit.
*Keep in mind this company will attempt to contact you outside of normal airbnb norms "airbnb" inbox. Even after telling them my text messages/calls won't work during my trip they were still trying to get into contact with me via these methods. (Made phone calls using someone elses phone)
