Just okay, and that's the problem
I checked into the Curtis hotel for training from July 15th-July 20th. I was not impressed with this hotel. I had high expectations for this hotel, because it is a Doubletree by Hilton. That comes with certain standards. I did not feel like those standards were met during my stay.
The room was great when I first checked in, but after staying there for one night, I should have asked to be moved to another room. All of the issues with my room happened after I recieved my regular Hitlon member courtesy phone call asking if everything in the room was okay and if i needed anything else. The first problem I encountered was that the left door to my armoir would not close. I realize this was not a big deal for most people, but it bothered me everytime I looked at it that it would not stay closed. The second problem I encountered was that the dead bolt on my door was screwy. Sometimes it would lock, but most of the time it would not. I could never figure out how it locked when it did. Other minor things I noticed that the front desk could not fix was the lack of a bathtub (standing shower only) and a lack of towel rods. 
I did tell the front desk (twice) that I was having trouble with the dead bolt on my door. They said they had sent someone up there, but it was not fixed during my stay. I also had issues with getting my newspaper. Two days during my stay I was out of my room by 8 AM and both times the newspaper had been delivered, but I did not get one. I don't know if someone stole mine, or if they forgot to put one out for me. It seemed odd since my coworkers who were staying in the same hotel had newspapers, but I did not. Also, I did not receive a receipt beneath the door the day I checked out. I had to go down to the front desk to get a copy of my receipt for my stay. 
Also, I know a lot of people like the themes on each floor of this hotel. I did not feel like my floor had much of a theme. I was on the 7th floor (Laugh Out Loud floor). It just seemed like a few funny pictures, and that was it. If you are going to have a theme on every floor, make it noticable. 
The one area I cannot complain about is the front desk. Their service was excellent. I received a free cookie when I arrived as well as helpful advice from the lady who checked me in. They handled my complaints with the room and my checking out process with ease and great customer service. My expectations were exceeded in this area. 
My overall stay was okay. I expected it to be good or great. For the price, I feel like I should have received a better room. Next time I am in Denver, I will stay at the Courtyard Marriott which was down the street from my hotel.
