So I am making one entry just for this. I hope this could be of help to all who are interested.
Here are the maps of RITM-ARG
Private car:
When coming from QC, Manila, Makati, Mandaluyong and Pasay take the South Expressway-Skyway and exit Alabang, then turn left on Filinvest Avenue. If coming from Cavite or Paranaque, take the Zapote Road, then turn right on Filinvest Ave, before Alabang. If coming from the south, Bicol, Quezon, Batangas, Laguna, take the SLEX or the National Road and once in Alabang, exit at Filinvest. Follow the map and you will see RITM on top of a hill. It is a white building on the right side.
Public Transportation:
Get a bus going to Alabang if you're coming from Q.C., Manila, Makati, Mandaluyong, and Pasay (via EDSA-South Expressway). Take either the bus or jeepney if you're coming from Cavite, Sucat, Paranaque (via Alabang Zapote Road). Take the bus if coming from Bicol, Quezon and Batangas. Take either a bus or jeepney if coming from Muntinlupa or Laguna. Get off at Alabang. Ask how to get to a jeepney or FX and ask the driver to drop you off at RITM.
Once you are in RITM, just ask the guard where ARG is. Once you are there, look for Maram Bartolome, Ellen Domingo or Let for assistance. Tell them I referred you there.
