"Good"

Location and layout. Rooms were elegantly designed with lots of light sources and blinds. Loved open concept. Refreshments - complementary lemon infused water, fruit, coffee & tea Socialization opportunity in lobby - games, ample seating, wi-fi, etc.

For the entire time an entire section of the floor was cordoned off due to construction so we couldn’t use stairway to quickly get to the lobby from the second floor where we were staying. Service could be better. Had to request service multiple times before we got it.

"Nice but will not stay again because of all the extra money"

5.0

It was very clean and staff was friendly.

Was very unhappy with the parking. I already paid a good amount for the room for 1 night and then had to pay to park . I can see if I was there for a few nights but for 1 night at $30 and my car next parking lot over from the hotel or pay $38.00 for valet parking. Was not happy about that . Then another $75.00 deposit . So a total of $105.00 extra after you get there . I was not happy about that .
