This property was in a great location. We visited the River Museum and Aquarium, which is right next door. Justin, at check in, was very friendly and helpful. He gave us some great recommendations for places to eat and have a beverage. We greatly enjoyed 7 Hilla Brewing Company and the famous hamburger at Paul's Tavern. We also enjoyed the hearty breakfast at Tony Roma's with the incredible view of the river.
