A Back Bay townhouse on Commonwealth Avenue has sold for $21 million — a blockbuster deal that marks the highest home sale in Boston so far this year, according to the listing agent.

The property at 59 Commonwealth Ave. is a single-family townhouse built in 1910, located steps away from the Public Garden, the Esplanade, and the Back Bay shopping mecca.
