Mark's place is at a quieter intersection but still a close walk to downtown (and also right across from a Circulator pickup). The check-in codes made it really convenient and easy. In-unit laundry with a really nice machine was downright dreamy. DC went from being 94ºF to 65º to crazy thunderstorm apocalypse while I was there, so I was especially thankful for the really effective thermostat.
The whole place is spotless and a professional company services linens and maintenance. Perfect for a business traveler who would otherwise be in a hotel.
