We’ve lived in Northern VA about 25 miles south of DC for six years and enjoy it. I work in Crystal City right next to the Pentagon and even that isn’t a bad commute every day. There are lots of things to see and do and, while the traffic sucks, there are a gazillion commuter options, including a very strong Uber/Lyft scene, the best subway system anywhere IMHO, commuter rail, and bike/scooter-share if that’s your thing. If you’re into live music, the Clarendon area of Arlington is great every weekend. We used to favorite a place called Iota for great local bands, food, and drink. As others have said, you’re a short (distance-wise) drive from some of the most beautiful areas of the country with the Appalacians, and taking your significant other on a winery tour through the region southwest of the city is strongly encouraged. The National Harbor is great and the MGM Grand resort and casino opened there two years ago as well.
The high-crime area is SE DC along the I-295 corridor in Prince George’s County, and there has also been a strong and violent incursion by MS13 into the Springfield and Manassas areas (~15 and 35 miles south-southeast of DC, respectively) over the last four years. The Air Force made a very pointed note to stay away from those areas while I was on active duty, so be warned. Thankfully, our town has been spared, probably due to the cost of living, LOL!
Good luck, Cooper!
