We had a great overnight stay at this property. 1/2 hood, 1/2 not - but easy and comfortable. Parking isn’t free which sucks - $15/day - that parked sucked considering we weren’t in the city. But staff was nice. No free breakfast. Balcony room was great on the top floor!

I enjoyed the stay, and the event I attended there was excellent. However, I think it is unconscionable to charge $65 to valet park when the garage is located down the street from the hotel for a cost of $6.00, but due to weather or if you are leaving in the early morning hours when it is dark and traveling alone (as was I) it is dangerous to have to enter the parking lot alone. I also thought the additional $50 early check in (I arrived at 12/check is at 2:00) was a bit unreasonable.
