The staff at this property were incredible. Everyone we talked to was friendly and helpful. I even left something of value behind and they had it shipped to me and I am ever so grateful. The room and the amenities were great and the hotel is in an area that feels safe and has a walking path nearby and also shopping and dining. We would definitely stay here again.
