The photos are outdated, they do a poor job of maintaining the place. We were in 976. The mirrors were scraped up and cracked, the kitchen cabinets are a mess (crooked drawers, one missing the front all together, you just see the particle board and nails on the front and it was pushed in so you couldn't get at what was in it), gaps in the floor, stained walls, etc... It felt like that cheap apartment you rented in college.
Our unit was in the Derby tower which was a pain to get to from the parking garage or through the Cosmopolitan. It requires one elevator, then walk across the building to another elevator, then walk back across the building, up a half flight of steps and then the third and final elevator.
Check-in was supposed to be at 4pm, but they were still cleaning it and we couldn't get in until 4:45pm.
On the positive side, the cleaners did a great job, everything was very clean.
