Our Apartment is located the heart of the Crystal City in Arlington and it has very large living room, dining room, kitchen, and balcony.
8mins walk to the Metro on the blue/yellow line.
We are 5 metro stops from DC or a 5-10 minute car ride.
You can also bike into DC along the Mt. Vernon Trail.
I have 2-cats[July(2Y) & June(2M)] with a wonderful, distinct personality.
The person moving in would have to be OK with living with it.
