I loved everything about our evening here. O Mansion is a truly stunning place for people of all ages. It was the perfect location for a book launch. The guests enjoyed hunting for the secret doors and passage ways throughout the mansion fore the event started. The venue contributed to the wonderful success of the event as well. What a fun place to be!
