Freeway noise, bugs in bathroom
This was our first stay at a Comfort Inn. This was also our last stay at a Comfort Inn. We booked 3 nights. We stayed less then 12 hours. 
As we checked in there was a women with 3 very unruly little children telling her kids and a staff member of the hotel how nice this hotel was for "letting" them stay there. 
Our room was facing the freeway (which I had requested that we did not have a room on that side of the building). We had almost no sleep (4 hours max) because of the noise from the freeway. Then as I turned on the lights in the bathroom I was greeted by 10 or 12 tiny ants walking around on the floor and counter around the sink. We were on the 9th floor of this hotel, so I'm wondering what the bug situation was below us.
The wireless internet that was advertised as complimentary didn't really exist. There was a "Comfort Inn" internet with only poor connectivity in the rooms. 
Ok, no decent sleep, bugs in the bathroom, hotel possibly being used as a local flop-house for some neighborhood mothers with kids, no internet in the room which was a must for my computer and work issues. Sorry, but the basics weren't even met for me. I am in a hotel to sleep and feel comfortable. Those needs were not met. 
The administrative offices behind the check-in desk were an absolute mess, as a few doors were open into that area that I assume shouldn't have been when we checked in. This probably explains the problems at this hotel.
