Bruins center David Krejci has purchased a $1.9-million apartment at 236 Commercial St.

The four-bedroom penthouse features harbor views, exposed brick and a private balcony. Carmela Laurella of CL Waterfront Properties was the listing agent. Kelly Bruno of Re/Max Leading Edge represented Krejci.

Editor’s note: This story has been corrected. A previous version identified Krejci as a defenseman; he is a center.
