I visited Amman several times and stayed in a number of its hotels (Le Meridien, intercontinental, 4 seasons, ...). The grand Hyatt offered a reasonable standing, but in the future it would always be a second choice.
The room I got was on the street side. My colleague was on the pool side. On the pool side te view is much better and less noisy.
The security control at the entrance is an Burden and somehow represents an obstacle to visitors, if you intend to meet people during a business trip.
