The Mansion on O Street is SO special and unique. It’s a beautiful museum with 100 rooms to explore (and shop) and 70 secret doors to discover, while operating as a hotel at the same time. They have a variety of tours– Champagne, Treasure Hunt, Self Guided.. I chose the self guided option, and had enjoyed wandering throughout the many rooms of the mansion– even came across a kitchen that offers beer and wine for sale and a pool table waiting for use. The 70 secret doors were pretty challenging to find– I think I came across maaaybe 4 or 5. But the whole experience is so different and entertaining– exploring multiple floors of themed rooms filled with objects for sale, while getting disoriented from all the nooks and crannies and the natural rambling of the structure.
