Today i took Osmena-SLEX to go to Villamore area to pass through C-5 extension to go to cavite. I thought it would be faster than passing through roxas or macapagal. I ended up in Alabang! hhehe

what's the proper way to get to Villamore via Osmena/Slex?(without using the skyway)
I may have missed the airport sign..but I saw about 2 airport signs pointing straight ahead but I didn't see an exit.
