A Back Bay condo has set a new price record in an ever-more-expensive Boston luxury market. 300 Boylston Street, Unit #1005-1006, sold on Friday for $15.4 million dollars.

That makes it the most expensive condo sold in the city this year, beating out 776 Boylston St Unit W12A, which sold for $12.5 million on May 6. It also appears to be the most expensive private home ever sold in Boston, beating out even the $14.5 million sale of the Ames-Webster Mansion to a Saudi businessman.

Tracy Campion of the Campion & Company real estate agency, the buyer’s broker, confirmed the sale and said it is in an “outstanding building overlooking the Public Garden with a side terrace.’’ Daniel A. Mullin was the exlusive listing agent.

The 5,083-square-foot Back Bay residence has two bedrooms, 3.5 bathrooms, a two-car garage, a massive kitchen, a dining rom with a stone floor, and a panel library.
