What address on Baltic St. are you going to? It stretches from Cobble Hill east to near Prospect Park. Cheapest is by subway but LIRR might be a good alternative. By LIRR ($13), take Airtrain from your terminal to Jamaica Station and take the LIRR to Atlantic Terminal. Walk down 4th Ave. to Baltic St., any address below 600 is to your right. By subway ($7.25) take Airtrain to Howard Beach Station and transfer to the A subway to Hoyt/Schermerhorn. Exit to Bond St. and walk south on Bond to Baltic, any address below 400 is to your right. The area from Cobble Hill to near 4th Ave. is pretty safe, past 4th Ave. gets a bit "rougher".
