Hi Jen, to get to Alpap I Bldg. from EDSA Shangri-la Hotel, you can walk about 2 blocks to EDSA. From there, you have 2 options. :) Option 1: You can take the MRT to Guadalupe station, and ride a jeep to Ayala, or take the MRT to Ayala station, and ride a jeep to Washington. Option 2: Ride a bus from EDSA passing through Ayala-Buendia. Whichever option you choose, get off at Ayala Avenue cor. Paseo de Roxas. Landmark is Robinsons Summit Center. Turn right and walk about 1 block, past Insular Life and PS Bank Center, until you get to Sedeno. Turn left and walk about 4 blocks, past Valero, Paseo Parkview Tower, San Agustin, and Liroville Apts., until you get to L. P. Leviste. Alpap I is about 3 buildings away to your right. Here's a link to the Google Map of the area:
