。
She was kind enough to show me the way.
Literal
She [topic-は] kindly [emphasis-も] me [to-に] way [object-を] guided-for-me.
案内する (あんないする) means 'to guide, to show around,' covering both giving directions and physically accompanying someone. The に marks the beneficiary (私 = me), and を marks what is being shown (道 = the way). In Japanese, you 'guide a way to someone' rather than 'show someone a way.'
