Union station is absolutely beautiful. Our room was on the first floor, although we were high enough we could still hear traffic noise. We were also able to hear noise coming from the hallway. our room was close to the main open lobby and away from elevator.
Our room had 18foot ceiling which was spectacular, the decor is tastefully done, the room had free starbucks coffee, bottled water.
The hotel itself offered coffee and scones in the am & cheese & cracker and ice tea, lemonade mid afternoon. no big buffet. We never ate at the restaurant, it was quite pricey.
No shuttle service to and from airport which a downfall for a Marriott hotel.
no swimming pool or sauna.
