The way you did it there is the same way we did ours as well. We had the same thing, no street number .. just the barangay.
The consulate won't mail anything to her anyway there. The packet some consulates mail out is not mailed in the Philippines, you retrieve it online once the consulate receives it from the DOS. Anything you need prior to the interview you should be able to get and prepare ahead of time on the manila consulate website or via emails. I personally loved the way Manila consulate does it, we were able to be way ahead of the process every step. Depending on what kind of access your SO has you may consider downloading all her forms for her here and sending them to her VIA fed ex. You can fill all the info in for her and she just will need to sign and date. I found that the cafe's there are not very helpful in downloading, printing documents you need there. Good luck !!
