Sorry I'm just getting back to you about this now. I was in a rush when I left and forgot to email you about the glass piece. I did knock it off of the tv stand when I attempted to reboot the router (internet was down during my stay). I even took a pic of the glass piece to remind myself to tell you about it, but still forgot. It still had a price tag on it from HomeGoods. It was $12.99. Send me your PayPal email address and I'll shoot you $20 to take care of it.
As far as the keys go, when I was leaving there was a guard (I think he was a guard) in the lobby when I walked out and asked him for directions to the office where I was supposed to return the keys (I believe it was on the other side of the building) and he told me to just drop them in the mail slot located in the office at the lobby, which I did. Surely someone found them, or they are still there? Sorry about the confusion
