It IS in an underground lot (very likely) at a hotel. Maybe no one noticed anything, there is already 10 HPWCs there. If it was on the side of the road maybe it would get more noticed.
Please don't create fake sites like this. Right now it's listed as a Chademo and a Tesla HPWC. People might drive here expecting one of those. It makes Plugshare less reliable.
Plugshare needs to make it more obvious that superchargers shouldn't be added manually.
I read that the restaurants on the property validate, making parking in this facility free. That makes me think there will be an attendant at least part of the day, and perhaps an option for less than $35 to charge.
Also there was a hint that the parking does not belong to the Hotel, so asking them for details may not provide much satisfaction.
