Tedd's place is wonderfully located right right between Dupont Circle and the Foggy Bottom metro, so it's super easy to get around to just about anywhere. Up on P street, just a 5 minute walk, you can find all the restaurants and amenities you need for the city. Walk to Foggy Bottom, and you can get various metro lines and the shuttle to Kennedy Center.
The place is a little dark inside as it's a basement apartment, but there are plenty of lamps inside to light up the place. For the summer, it's nice and cool and comfortable. There is plenty of bedding and towels, and you have the basics in the small kitchen-two burner stove, dishwasher, full-sized fridge, and some basic dishes for a few people.
Being down below street level, it's fairly quiet for what is a busy area and you can definitely get a good night's sleep here. For visiting DC, this is a great spot to be located in and has all the basics you'll need without any pretentiousness.
