You asked if you got an upgrade. - yes you did.
You asked if you had access to the CL lounge- yes you did

Did you ever ask if you received a high floor room with a view? It does not appear that you did.

Best available room does NOT mean specific room type you requested in the note son your reservation. I think the new wording is very confusing, but I don't think your particular checkin on this date had ANYTHING to do with this. If you had recieved a high floor room with a view that did not have a balcony and was not on the CL level the hotel would not have been able to answer "Did I get an upgrade" with yes. They would have to say no. Because at this hotel, a high floor standard room with a view is not any more $$ than a lower floor room unless it includes concierge access, and for Gold's and Plat's ALL rooms allow concierge access.
