Don't forget that there are hills around the Andaz, including when walking to/from subway stations in the neighborhood. That part wouldn't be so good with little kids, including those in strollers, although some of the hill can be avoided most of the time (not sure about opening hours for these doors and elevators) by exiting the building on one of the upper levels (with restaurants etc.) that leads out to the upper part of the little park and amphitheater along the side/back of the building.
