Great decor, terrible noise
Of course, this is the Hard Rock Hotel, so it looks good and has a cool vibe. My room was clean and I really liked the decor, especially the bathroom. I was in town for a convention and the location of this hotel can't be beat. The convention center is about a 5 minute walk, door-to-door. 
The problem was the noise. I was on the east side of the hotel on the 9th floor, but I kept waking up to people leaving the bar on the ground level, crossing the street and yelling. All the way from the 9th floor - I couldn't believe it. Also - there are train/trolley tracks nearby, and the dinging bell kept waking me up, too. Of course, the worst part was the "Wintervention" party on Sunday night. There were wayyyy tooooo many drunks stomping and yelling through the hallways. I have never been in a hotel of this caliber with such thin walls. I know this is probably considered by most people to be a "party hotel," which is cool, but the rooms could definitely use some quality interior and exterior sound-proofing. Super frustrating! I was essentially paying for a place to sleep, but I couldn't even do that. To me, the cool decor just didn't make up for it, so I rated my room "poor."
Just know that, if you plan to sleep here, you may need earplugs.
