What an incredible (and eclectic) experience! Although we didn't stay as hotel guests (this would be quite an unusual experience for that - be sure to verify with the staff about whether your room includes a private bathroom, and during what hours visitors to the museum might be right outside your bedroom door!).However, just touring the house(s) as a "museum" was fascinating and well worth the visit. Although a bit away from the traditional Washington DC Mall visit, the "Secret Door Museum at the Mansion on O Street" is still a must see! Especially if you visit early (it's better when it's not crowded), and then lunch can be a few blocks away at the incredible Kamers (bookstore and) cafe!For anyone looking for something a bit beyond the "Archives and Smithsonian" (which are great reasons to visit DC!), this place is worth adding to your itinerary!Rooms: Very eclectic. Be prepared for a LOT of extra items (some might describe it as "clutter") in the rooms. Fascinating variety of items, many autographed or very unusual items.The rooms are excellently themed, providing a nice continuity to the items that are present, but removing items from the bathroom or closet so that you have space to put your clothes or suitcases away may be a surprise to some guests.Nearby activities: Be sure to visit Kamers (bookstore and) Cafe - only a fee blocks away on the other side of Du Pont circle.Walkability: The walk from a few Metro stations is perfectly fine on most days (a few blocks), but bad weather or extreme heat may make a RideShare (e.g. Uber, Lyft, etc.) more desirable for some.
