There are other reviews which mention issues with check-in. Our experience was nothing short of fabulous. We went for the NYC Marathon … I received a text the day we got to NYC welcoming us, had a very easy and fast check-in (even about 30 minutes early), and received communications throughout our stay. Each time we asked a question to the front desk, they were very nice and knowledgeable. The one night we ventured to the lobby bar, the bar staff was great, even coming up with a new drink and having us taste test. The room was clean (only picky thing I’d say is the carpet could use a cleaning) and we looked directly out over the Oculus, the north infinity pool of the 9/11 Memorial, The World Trade Center, and the Hudson River. I really have nothing but good things to say about our stay at the Millennium Downtown.
