Room were clean, well appointed and everything was working great. The improvements that are needed to make it 5 star are:
1) The water flow is bit slow and thin in faucet as well as in the shower.
2) Breakfast choices are very basic (automated Pancakes, Fruits, Yogurt, Grit, Eggs, etc) and nothing exciting for Hilton standards. Some addition like Oatmeal, Croissant, Diabetic friendly items will make it feel and taste good.
