Dartmouth Street spread asking $4.75M covers converted townhouse’s third floor

The seven-room, 3,440-square-foot Unit C at 314 Dartmouth Street in go-go Back Bay attains that size in large part through occupying the building’s entire third floor.

The townhouse it’s in was built in 1871, and later converted to five luxury units.

Unit C is on sale through Gibson Sotheby’s for $4.75 million. That tag entitles a buyer to the location and the scope, of course, as well as to touches such as four fireplaces and direct elevator access to the condo’s foyer.

There is also a parking space out back.
