I believe it's a standard for just about every corporate hotel chain to verbally confirm the hotel location when confirming reservations, and if you received an email confirmation, it would definitely be listed there. If that did not take place, the blame gets shared equally amongst the MSC, hotel and shopper, I say.
Experience tells me that if the location is not confirmed, I will need to make a call to the hotel in advance to confirm the reservations....and to not trust MSCs to supply correct addresses and phone numbers. They mess that stuff up all of the time. I would consider that to be due diligence as a shopper.
