Our second time here. It’s a beautiful property and looks like a castle with the stone walls and grand staircase. The beds are particularly comfortable. Johnny Rocco’s restaurant on site has excellent food and carefully caters to food allergies especially gluten free friendly. Highly recommend

During our visit we were awoken by the fire dept at 4:30am and had to evacuate the building for Carbon Monoxide detected in the building. After about 90 mins we were allowed back in but there never was any acknowledgment of the issue to us like what happened or apology or please come back again; nothing.
Watching from far what was going on.
