No-Holds-Barred Best Gym in Hoboken?

Hey everyone! My job just started offering a monthly stipend specifically for a gym membership. If I don't use the money for that, it's gone. With money as no object, what would you say is the best, nicest gym in Hoboken? The type you can't afford but wish you could, lol. Preference is for downtown and a place where I can just workout by myself, no instructors/classes/etc necessary, but I'm open to hearing all of your suggestions! Thanks in advance.
