。
She was kind enough to show me around town.
Literal
She [topic-は] kindly [emphasis-も] town [object-を] guided-for-me.
When 案内する takes a place as its object (町を案内する), it shifts from directional guidance to showing someone around — giving a tour, pointing out sights, sharing local knowledge. The benefactive ~てくれた frames the action as an appreciated favor done for the speaker.
