the mansion is one of the most unique and intimate environments in the world.

nestled in the center of washington, d.c., only minutes from the white house and georgetown, the mansion on o street's discrete private club offers a respite for discerning guests.

the mansion is a way of life. it's where presidents, prime ministers and religious leaders come to relax. it's where ceos inspire their employees. it's where business associates and friends meet for drinks. it's where artists and authors find their muse. it's where families gather to create special memories and it's where the music plays on, beyond forever. live heaven, live life, at the mansion

no request too large, no detail too small.

The adventure starts with the website, which uses an alternate site organization structure that many of us have become accustomed to. This diversity of thinking permeates throughout the experience to the museum itself. The experience is a celebration in alternative thinking. As to the hosts, I was pleasantly surprised to be greeted at the door by the owners and humbled to receive such a personal welcome (as well as tips on where to get excellent food as we waited for friends).
