Please help me how can i get to DOST Region 4 office in Los Banos, Laguna if i'm coming from Batangas? thank?

Star Tollway, by the way where in Batangas, there are several options, anyway uming Batangas City, Lipa..but not from Nasagbu..Star Tollway to the end..exiting at Sta Thomas..turn right, sign says you are going to Manila...whenever you see a sign to Calamba..take it..Los Banos is after that.
