This renovated 5-BR, 4.5-BA townhouse at 344 Marlborough Street in Back Bay is described in the listing as "extra deep." See why. Its 5,388 square feet seem to just go and go—all the way to a walk-out deck. Bonus crazy luxury touch: the kitchen appears to be in the center of the parlor floor. No one puts that baby in a corner. All yours for $3,995,000.
This one's pretty neat. Located on an achingly quaint Beacon Hill cul-de-sac, the 3-BR, 2.5-BA, 1,815-square-foot townhouse at 5 Rollins Place dates from the 1840s, and was renovated in 2001. It's got four fireplaces and central air. Last traded in May 1997 for $547,500, now yours for $1,350,000.
