Not worth the money
I stayed at Hilton Union Square over Labor Day weekend. I arrived at the hotel around 5:30PM on 9/1 and tried to check in but was told that only double rooms or smoking rooms were available. The person who was checking in was very rude and told me that my reservation does not guarantee what type of room and told me to wait 50 minutes if I wanted a room with a king bed. When I told him that my reservation did guarantee what type of room, he quickly changed what he was saying that told me that the room is ready but that I will have to wait 50 minutes because they are cleaning the room. When I started to argue, he rudely cut me off and told me that he does have a room available. I was pretty upset but swallowed it because I didnt want it to ruin my trip. BUT when I got to the room, the pillows had hair and black stains on it. I asked front desk to replace them, but the replacement pillows that came almost an hour later had make up on them. 
I should've just stayed at a cheaper hotel down the street.
