Didn't use the bar. Breakfast items extremely pricey. Waitress was excellent.

The Valet parking was quick and easy. Plenty of shops, restaurants and attractions nearby. Anthony was extremely helpful when checking us in and out.

Excellent location and very clean. Pristine rooms with a spacious bathroom.. The bed was also very comfortable however, for a hotel in this category, we felt it lacked some amenities and atmosphere .there wasn’t much happening in the hotel and many things seemed to close quite early. Our room was supposed to have a city view, but it almost faced another apartment building. We also tried the Hotel breakfast one morning and found it quite pricey. Overall comfortable stay in great location, but it didn’t fully meet expectations for this level of Hotel.

Hotel had no information on the reservation. Thankfully I had the confirmation email from Expedia that helped resolve the issue.
