Very nice place. Quick walk to downtown. Parking is limited and valet parking is pricey at $45 per day. The perks are good. Two free bar specialty drinks per night and $25 per day to spend in the facility, which covers breakfast. Breakfast is all you can eat with an ample and very nice buffet, plus eggs to order. The lobby bar is great. We could only get the specialty drinks in the lobby bar, which was not ideal. But was okay because the roof top bar staff were struggling. It is a nice environment but people were waiting 30 minutes to pay their bill and it was nearly impossible to get a drink at the bar. Maybe this has been rectified. Overall, I'd go back.
