Booked accessible room. Arrived at hotel, no problems checking in. Long walk with confusing signage to get to the room. At one point you can miss a hallway and end up going all the way to terminal. Elevators are only at one end of floor. Guess which end they placed accessible rooms?Yep, opposite. Also the design of hotel is not ADA compliant in any fashion. You have lots of uphill walking. A person in a non-electric wheelchair would never make it up alone.

Once in room, obvious I was 1st guest.
Issues -
Shower had no fold down bench installed as is supposed to be for accessible.
No shower curtain (common issue in all rooms).
Construction dirt still in shower.
Water pressure just about nil
Water temp, lukewarm at best
No clock in room/call for wakeup call/informed hotel doesn't do wakeup calls even though no clocks installed in rooms!
Curtains are electric floor to ceiling and are supposed to be in a track. One isn't meaning it doesn't close correctly without major fidgeting.
New towels had obviously not been washed.
One outlet, and you couldn't use both plugs at same time.
Tray full of toys and candies. No prices, you must go online. Minibar refrigerator not fully stocked.
Phones are rotary. Not very practical. Phones don't always work either. I called and asked for manager. No problem when I would call. When they would call, they could hear you, but you couldn't hear them. Found out this is a known issue, they have to find a phone that will connect properly if this happens.
Housekeeping randomly knocks on door and tries to enter. Obvious they had no clue which rooms needed what done, plus when it needed to be done.

No food service, they had just gotten shut down by health department. Even then, before it was only very limited service. They were telling guests to eat in terminal. Theres not much landslide at any terminal.
No waiting taxis for pickup. Airtrain requires entering T5, going to opposite end, crossing bridge, and boarding. Other option is to to cross street, which has no crosswalk to enter via parking garage.

Bag storage - they don't store them in a secure room. Instead they place them on the old bag belt behind the counter. One could easily walkup and walk away with a bag with no one noticing.

Finally employees just seemed to not care. It seemed they were worn down by all the issues, leaving no willpower to help.

I do think it'll become a great hotel. However they should've held off opening. They causing damage to their image by operating in the state they are. This is especially true, as they nowhere note that hotel is not fully ready. Everything has been published as the hotel being open, fullstop, no asterisk.
