Stayed here multiple times. I've stayed in a City View room, a Terrace-Studio. I love the bathroom, it is spacious and clean with a jet tub. Just lower down the blinds when using the bathroom so, you don't have a peep show from the bedroom. There's always good views in most rooms.
Lots of variety in the restaurants, I tried most of them and love them all, Wicked Spoon, The Henry's, Holsteins, Comme Ca, Jaleo, China, Poblano and D.O.C.G. Pricey but lots of choices in the menu.
The swimming pools during summer is always a party scene. During the winter, it is turned into a skating rink. Kids age 5 up also can play video games by the swimming pool, no charge, just leave your drivers license when you borrow the video games and game controllers.
They have the Marquee if you like dancing and there's a separate line to get in if you are a guest at the hotel.
What I love most is the scent at the Cosmopolitan lobby, when you get in, it smells like a combination of cucumber-avocado. You don't get the smoky scent on your clothes when you hang out at the lobby or even by the slot machines. Unfortunately, they don't sell their signature scent.
I love the Cosmopolitan and it is always the hotel I choose whenever my family and I go to Vegas.
