First the internet didn't work or correction it was 1.48 gigs which is a very slow connection. So I went to the front desk and even though it was like 11:00 p.m. The woman said that the guy that fixes that is supposed to be in soon. The next morning it still wasn't fixed which completely screwed me on work. I had paid for full 7 days but I had to demand a refund. This is no lie the girl at the front counter told me that the internet is slow in Maryland Heights. I had to tell her I was going through a divorce and I own a house in Maryland Heights and my internet is at any time at least 200 gigs. She went on to argue with me and saying that she worked at McKelvey and Dorset for her other job and she knows for a fact that the internet is slow there. I told her that's funny because the entrance to my neighborhood is the first neighborhood after McKelvey and doors it so she was full of it. To top off my 100 plus dollar one night that they didn't do anything to correct I met a maintenance man in the hallway and he said yeah people have been complaining about that lately. So it wasn't just me and they were full aware and just playing dumb. The breakfast... I prechecked that they had biscuits and gravy. But they didn't have biscuits and gravy. They didn't even have eggs. And when I asked the woman coming out of the kitchen if the only hot breakfast was from the overcrowded waffle makers she responded, "What you see is what you get."
