Anything's possible, and while sharing folders would make it easier, it's
certainly not the only attack vector.
If Windows Firewall was turned on at the time, and is in "Public" mode, or
in any mode with no Exceptions enabled, your computer is as safe as it would
be if you were using public Wi-Fi (which you were, however unintentionally).
Which is to say, reasonably safe. If UAC was turned on, you'd have an
additional layer of protection against remote malware installation. Likewise
antivirus/antispyware. And as security conscious as you sound, you probably
have all of the above.
It's not really possible to answer your question, even if we knew enough
about your computer config, which we don't. Any computer is hackable. But if
you had Windows Firewall, AV/AS, and UAC, in addition to the many layers of
OS hardening in Vista, and the bad guys only had a couple hours' window of
opportunity, there are probably a *lot* easier targets in your apartment
building than your computer. And the bad guys are lazy.
If you're still concerned, restore from a backup made before the router was
open. Or, less Draconian, do a System Restore to before that time; you won't
lose any data that way.
