Mark's place is amazing! The location is perfect and the view (especially of the Bellagio fountain) is absolutely breathtaking!
My boyfriend and I were in Vegas for his 40th birthday and we could not have picked a better place to stay. The hotel itself is great, and with the added bonus of having no resort fees and free valet, I don't think you'll find a better deal on the Strip.
If you're into gambling, the Aria (and the Cosmopolitan) is a short, pleasant walk next door.
Mark had several wonderful suggestions for food and activities, and was very responsive to my questions. Can't wait to stay there again!
