It was so comfortable and uniquely and beautifully decorated! There was so many awesome areas to explore inside and outside of the Grain Bins. Food provided for breakfast was fresh and hot. There was perfectly cooked bacon, scrambled eggs and really moist corn muffins with homemade mango preservers! We were welcomed with fresh, homemade plum bread. Instructions for everything available to utilize and operate were easy to understand. I can’t wait to go back and I will tell all my friends and family about this unique and relaxing place.
