The staff could of been a little more pleasant during checkin like pointing out elevators, hotel amenities and dining options. Other than that, no concerns with room or parking.

The hotel had a unique design and a great location. The walls were thin so we could hear our neighbors, and one of our pillows had a stain on it. Maid service replaced the pillows for us with no further issues. Staff was friendly.
