Grand Boston home is a spectacular sale

The single-family Victorian home at 297 Marlborough St. in the Back Bay is among the city’s spectacular sales in September. It sold for $4.575 million.

Beth Dickerson of Gibson Sotheby’s International Realty was the listing broker, and Daniel Mullin of Daniel A. Mullin & Associates was the selling broker.

At the back of the house is a huge kitchen with extra tall bay windows that overlook the garden.

The kitchen is equipped with high-end appliances, custom cabinetry and granite counters, and the center island has a mahogany top.
