8.4/10 Very Good! (2,168 reviews)
Decent room and the staff at the front desk and restaurant were friendly and helpful. The front desk area is cramped and confusing (i.e.) once you get your key card from check-in, it is so tight in that area that that it’s unclear how you get out of the area without pushing past the people in line ...

Everything was top notch except the teeny tiny bed my husband and I had to share. We have a king bed at home. Not fun sharing a double. And we are not big people.
