What a strange recommendation.
Working downtown, I’d suggest finding a place downtown if affordable for her. Other areas to look at would be Clintonville, Grandview, Upper Arlington, Short North, German Village, etc. All are super easy commute to downtown. Could even ride a bike during the summer. A little both further commute would be Hilliard, Dublin, Worthington, etc. Stay away from northeast and east. Commute times are killer.
Do you have a ballpark idea of how much she’s looking to spend for rent?
