Absolutely! I have heard that the area used to be dangerous 4-5 years ago but it's so much better now. There are so many great restaurants, coffee shops, and ice cream shops. They can go for a nice walk in the park(s) and easily spend a good few hours exploring. I have been there 3-4 times in the last few weeks and it never felt unsafe. Metro is probably best way to get there, but there is street parking available as well. Eastern Market is also a very short walk if they want to check that out! :)
It used to be a very dangerous housing project over there called Author Capper aka 501 boys but it was demolish and this is the new look of it, however there are still projects that surrounds the area one of the housing projects on the southwest side across the street from the baseball stadium is called Greenleaf Gardens Southwest and 106 and park and up the street is Potomac Gardens and another housing project called 1000 which is also on the Southeast side, But for the most part The Navy yard area is cool even though there were a couple of shootouts after the game at the ball park and one wrong turn can have you in the hood you should be OK lol
