We are just in the process of moving out of Locust Point but it was fantastic for us when we were in your position - I commuted to college park, my husband commuted to Ellicott city, and we were young professionals in the city with no kids. Fed hill has a bit more nightlife but I prefer the slightly calmer pace or LP personally. If you want walkable coffee shops, ceremony coffee is excellent in that area though. :) can’t go wrong with either
