I attend 1 to 2 conferences each year that typically put me in the Washington Hilton Hotel. Though a great place, some time it's way too pricey for the budget I have. This year I chose to explore the vacation rental route as I use this strategy all over the world to great success. I discovered LUXBnB and the wonderful property they have just across the street from the Washington Hilton. It's a great building with wonderfully appointed and finished rooms.
The owner's have it all down. From the ease of getting access (they send you a 10 digit special code for the front door and your unit door which you can change once you arrive to anything you wish) to the way the room are appointed. Great towels, comfortable linens, smart yet efficient space design.
I see there was one complaint about noise and yes the building sits on a daytime busy intersection yet I didn't have any trouble after 10 p.m. until about 7 a.m. with street noise. I slept very sound and I live... Plus
