Worked just fine for two nights at the convention center for a conference, since all I needed was a place to shower and sleep. Two knocks against it though:
First, the email confirmations make clear there's a $40 charge for early check in, but there are no instructions on how to get an early check in (the instructions say the key code to access the room will not work before 4pm).
Second, and more concerning, the smoke alarm in the room was covered, thoroughly and intentionally, by a plastic bag. I don't know if this was management or a prior guest who wanted to smoke in the room, but it didn't feel great.
