Stayed for 6 nights. Loved that there was a 24hr convenience store in the basement. The only thing we didn’t like is on the 5th day we requested a room cleaning and they half cleaned leaving the bed undone. Other than that it was an enjoyable stay. The staff were nice and helpful. Restaurant food was good.
