The Vdara is a nice boutique style hotel set right next to The Strip. It has easy access to it's neighboring hotels like the Belagio and Aria. It's a valet only property but valet is covered while you're staying in Dario's place. Check-in is really easy at the front desk and you can use the hotel just like any other guest (you must put a credit card on file when you check-in).
The room was just as it appeared in the pictures. It was very clean. While it wasn't a Strip view there was a great view of the valley. It was also high enough up that you couldn't hear any road noise. It's close to the elevators but unless the people in the hallway were exceptionally loud, which only happened once, we hardly knew anyone else was on our floor. It is equipped with everything you might need for an extended stay but we didn't take advantage of most of these amenities. We kept a few things in the fridge but didn't use the rest of kitchen as we ate our meals out and had enough clothes so we didn't need to use the washer/dryer. The main bath is quite large and had everything we needed as far as soap, shampoos and towels. More of these were just a phone call away as well. It had two nice televisions and the internet worked well and was fast. The hotel also has at least two little robots that make room deliveries. If you can spend a few extra dollars that's a fun thing to try (have your camera ready).
I'd recommend Dario's place. It's a nice room in a good location.
