This four-story Carroll Gardens townhouse is impressive from the get-go. Located at 356 President Street, in a historic district, the 1869 home boasts a facade with an arched doorway, the original paneled doors and Italianate cast iron hand railings, and an impressive cornice. Inside, the historic details were recently restored, like eight fireplaces—five with ornate marble mantels—plaster moldings and ceiling medallions, decorative trim, and the original wood floors. On top of that, the backyard was redone by a landscape architect to include built-in seating and a bluestone patio. After all those upgrades, the impressive property just hit the market for a little over $4 million.
