Spacious, classy, and very clean. I stayed here in a group of 6 and we all had a great time. There were three bedrooms, each with a queen bed and an adjacent bathroom (in the entire rental, there were 4 bathrooms total). There was one air mattress that was quick and easy to inflate (no pump needed, you just plug it in - do this early though, it's loud!).
We mostly used Lyft during our weekend stay, but the location is not far from downtown DC (you can take a couple buses to get there, or the green line with a bit of walking). There's a corner store right next door that sells snacks, alcohol, and other essentials. Northwards you'll find other groceries, a liquor store, beer garden, etc.
We brought extra towels just in case, but there were plenty of towels and bedsheets for the 6 of us regardless. Several bathrooms included bathtubs, which was a nice surprise. Plenty of soap and toilet paper, and there was a tiny hair dryer.
The kitchen is complete with a microwave, stove top, and dishwasher, and Keurig coffeemaker. The kitchen is not well stocked (just coffee and vinegar), so you will need to buy basics if you plan to cook. Suggestion: stocking some tea as well as coffee would have been lovely.
There's a TV with access to YouTube, Netflix, and Vudu in the living room. The freshener used in the rental was very nice, but at times overpowering.
Overall, would definitely recommend.
