I would highly advise avoiding this listing and host. I did not get to see the unit because the host was unresponsive and did not provide check in information. I needed to book last minute hotel rooms and am out an extra $1,000.
This listing is owned by a company, every contact you are speaking to someone else who has no idea of the context of prior discussions. They break AirBnB terms of service by asking you to submit identification through another app, it may be an identity theft scheme.
If you want to get left stranded on the sidewalk 4 hours after check in, forced to spend an extra $1,000 to book a hotel room stay here, but I'd advise to avoid Sonder at all costs!
I've stayed in a dozen other AirBnBs and have never had an issue. To reiterate, it isn't that I didn't understand check in instructions, they did not provide check in instructions at all.
