Really nice hotel with great amenities .... lucked out and stayed in a nice suite overlooking the Bellagio water fountain. Walls are well insulated so not noisy at all. Has one of the best buffets (Wicked Spoon) and some great restaurants and bars (Chandelier). Has the very convenient sky walk way so you can cross the street and get to Walgreens :) Valet service was always very quick and easy.
My only knock would be the lack of a good sports book.
