Loud - or Paper Thin Walls
Either, for two nights running, there was a very loud party (Think Risky Business with the music and people laughing and doors slamming) going on next door to me or the walls are paper thin. I had to call down both nights and it did nothing to help the noise. Once was after midnight and once was before. 
I have a 3rd night scheduled for tomorrow night - I think I am going to find another hotel. 
Oh, in addition - there is a urinal cake lodged into the AC unit in the wall - so there is a funky smell in the room.... I am sure they thought it would help, but it made it worse. If I was not here for work along with others, I would have checked out after one night and not be suffering tonight. 
On the positive side, It is large and there is a refrigerator/microwave area in the room, they have free wifi and the breakfast that is included in the rate is nice.
