Disappointed. Stayed on a road trip from Texas to Illinois. Pool played a big part in choosing the property but was unavailable during our one night stay because they were working on the roof. Would have been nice if they offered a discounted rate because of that. Breakfast was not “English style”, just a buffet. Bathroom in room was smelly. The adjacent bar/restaurant and tavern in the hotel were enjoyable.

Love this quirky hotel right on the Delmar Loop. Comfy and fun. Our dog loved it too! Only issue was the AC was extremely loud and made periodic bangs that made it hard to sleep.
