Stayed Five Times
i've stayed at the Andaz property on 5th Avenue five times. It's not cheap, but there are some special things about this property.
the past two times, I used Diamond upgrade certificates. If you push a bit, you can be upgraded to a Splash Suite, which is on the corner of the building and has views of the Empire State Building and the library and up and down 5th avenue from the bed.
Diamond members also get a $75 credit for breakfast, which is exceptional food. If you order a muffin, though, don't expect to eat it with your hands. it's huge and topped with all sorts of goodies, which requires a knife and fork to dig into. The breakfast can be ordered via room service or served in the restaurant.
The standard rooms can be on the small side and some look directly into other buildings with no view. In general, there are a lot of different room types, so if you don't like one type of room, or the part of the building, ask to be moved. I have been accomodated when requested.
