Where: 157 Appleton Street
Square Footage: 2,523
The Skinny: 'Tis rarely a new Cambridge listing of more than $1 million, so let's spare a thought for this 4-BR, 2.5-BA in the Neighborhood Nine-West Cambridge borderlands (western Mid-Cambridge? Neighborhood Number Eight and a Half? If only there were a handy map to Cambridge's nabes...). Its 2,523 square feet have seemingly all been redone, with custom everything and what the listing calls "expertly placed lighting." And that redo, the seller believes, has earned the place a premium: It last sold just last winter for $625,000.
