Adams Morgan: $459,000

Co-op: 1840 Biltmore St. NW, #23

An original claw-foot bathtub is only the tip-of-the conversation-piece iceberg in this museum-like co-op. The foyer includes part of a confessional from a 19th-century Baltimore cathedral, though the structure serves a coat-storage rather than clerical role today, and complements the bathroom floor and its walls, which are made of marble from the same cathedral. Most of the kitchen counter top comes from the Library of Congress, which rejected certain marble slabs. A co-op fee of $832.50 and an underlying mortgage of $267 per month are perhaps the least whimsical things about the 1,200-square-foot, two-bedroom, one-bathroom unit.

Ballston: $450,000

Condo: 1050 N. Taylor St., #1-708

Were “Ballstonian” an adjective meaning “nice if slightly nondescript,” Ballstonian would certainly describe this two-bedroom, two-bathroom condo located one block from the Ballston Metro station on the seventh and top floor of a building that overlooks other condos and office buildings. The hardwood floors and light yellow walls throughout the approximately 1,000-square-foot space give the unit a sunny atmosphere that reaches its zenith at the condo’s most interesting feature: a small, glassed-in balcony sunroom. Two parking spaces, a community pool and onsite management come with a condo fee of $594 per month. (Listed by RE/MAX Allegiance)
