While amenities and being up to date are important, my main focus for a hotel is it’s cleanliness and how comfortable is the bed since I’ve stayed many places that while nice, if the bed is uncomfortable can ruin your stay. Our room at Omni was clean and comfortable. There were a few things that looked a little tired and could use updating but overall we had a good sleep and were refreshed for the next day.

From the moment we stepped into the Lobby, the excellence of the Trump was on full view, from being greeted by name and the glass of Champagne, the commitment to excellence was evident. Room service was spot on, hot and within timeframe promised. We can't imagine staying anywhere else!
