Big disappointment
Tower wing rooms are lacking charm - more like just old fashioned (other rooms are much nicer). Service was the bare minimum and no sincerity or warmth from front desk. Took 3 visits to reception to check in with very lengthy lines - first time room wasn't read, then had to wait back in line when first room was ready, then wait again for 2nd room - total of over 40 minutes waiting in line. Bellman on departure was incredibly rude.
Second stay and it really seems to have gone downhill. Not value for money for the US$800 we paid for two rooms for one night. Plenty of other hotels in close vicinity to Union Square that I would choose.
