I'm originally from Nyack, & love the town. Since there are no other hotels in the town -- strangely -- & I don't like the nearest motels, I've stayed at Hotel Nyack twice when visiting.
Sadly, its architecture makes it VERY, very noisy. VERY. Any noise in an adjacent area, hallway or room echoes loudly. In addition, when I booked for the weekend of my 50th high school reunion, (at a nearby venue), no one told me other high schools would be having theirs actually IN the hotel. Consequently, it was "party central" in the hotel. I have rarely in my adult life (of traveling the world & staying in MANY places), ever had to bang on the wall at midnight to tell the nextdoor people to turn their music down. AND I banged on the wall because the room phone didn't work!! Literally.
When I arrived initially the front desk gave me a "goody bag". Turned out it wasn't for our reunion! (I returned it.)
And then: When I arrived at my room after checking in, the door of my room was ajar. As a woman traveling alone, I called the housekeeping staff right away to check the room over, feeling very uneasy. The staff came to discover that the connecting door to the room next door was also unlocked!!
Honestly, I couldn't believe this all in a Hyatt Hotel.
Sadly, I guess I won't be staying at Hotel Nyack again, nor will I recommend it.
