What subway lines do you need to take from the Port Authority to the Metropolitan, please? Thank you.

From Port Authority, take the shuttle to Grand Central Terminal, there you can take the 6 train to 77th Street and Lexington. Walk to 80th street and 5th Ave. Is about a 5 min walk. Also, the 4 train stops at 86th Street and Lexington

There are places around the city where you can store your luggage for like $6
