Curbed Boston has found the city's oldest listing asking more than $10M: a five-bedroom, seven-bathroom, 8,600-square-foot townhouse that's been on the market for well over a year. Outfitted with an au pair's room and a full-floor master suite, the place is asking $12.5M—coincidentally, just the number of Boston's biggest sale of the year so far. [Curbed Boston]
