We loved our stay at Vdara on the 50th floor. It was just as depicted in the listing - great views, comfortable bed and bedding. Checking in was a breeze and valet parking was complimentary. (Just make sure you when you get your valet ticket that they know you are in an owned unit - they have to set it up properly so that the valet vending recognizes that your vehicle valet parking is complimentary.) The location is amazing - you get all of the benefits of a less busy entrance (ease for parking/valet and rideshare than the big casino hotel entrances), but still get the close in location to the other properties with fine dining and casinos.
The elevators were speedy - even during high traffic times (check in/checkout/ dinner time), I didn't have to wait long.
Starbucks is conveniently located near the elevators as is a small market place to get drinks, casual food (sandwiches, salads, desserts).
We didn't take advantage of the kitchenette cooktop, so we didn't need to request any dishes, etc. But we did love having the refrigerator for drinks and microwave to heat up coffee and/or leftovers. (Just be aware the fridge is a mini-fridge, so don't plan on bringing a ton of food that needs to be kept cool.)
It was pretty quiet. You can hear the Bellagio fountains if you listen carefully, and of course the helicopters doing tours. There are "blackout shades" but because this unit has panoramic views, they are split across three sections which does allow a significant amount of light in (both from the sun and from a giant screen on an adjacent hotel). If light wakes you, bring an eyemask.
Will definitely stay there again!
