The obvious advantage of Grand Hyatt hotel is the location - as it's right next to Grand Central station and a number of attractive sites. It has a very elegant lobby with waterfalls and high ceiling, but the rooms are known to not meet the same level of luxury. If you're on the picky side, you might not like the weird layout or the lack of tight security, but if you just want a comfy bed in a central spot for a reasonable price, you should be satisfied.
