Ever since I first stay at the Andaz 5th Avenue I fell in love with that property’s overall value proposition, especially for a Hyatt Gold Passport Diamond member. Their rooms are generally large for New York anyway, and they have a ton of suites, so Diamonds often get upgrades even when not confirming a suite upgrade at time of booking. And they offer Diamonds breakfast via room service as well as in the restaurant. (The restaurant is small and this makes it possible to accommodate everyone.)
And I absolutely loved the Park Hyatt when I first got to stay there back in the Fall.
However in Manhattan I tend to choose a hotel for a given stay based first on location and then price (or rather ‘value for money’).
