Further question regarding application of SAR passport - Wahington D.C Chinese Embassy address

Thank you for all your reply. I am told (by the Embassy people via phone in Dec) to go to the address:
2201 Wiscosin Ave NW Washington DC 2007. I tried to call but they never pick up now.

Now you told me to go to: 3505 International Place, NW Washington DC 2008. Can you please clarify which is the right one to apply for my SAR passport? Thank you.
