We stayed at Stephanie's place for 2 nights.
PROS - The lounge was comfortable and cosy, there is a wonderful arm chair that is amazing to sit in and relax after a long day of visiting Washington sights. Also there was a piano which I personally lived being a pianist. The windows opened for a lovely breeze on a warm night. The Kitchen had the basics to cook a meal and the bathroom had a good shower and a bath. Transport was great with the Metro a few streets away and if you want there are Lime bikes and scooters on the corner for rent, you can ride straight along one street and this will take you to all the attractions.
CONS- The bed was uncomfortable as it sagged in the middle. The sofa in the lounge was not much better.
The apartment was a little bit older then the photos suggested. The neighbourhood was a little bit of an issue and after seeing other neighbourhoods I personally think I would pay extra and stay somewhere else, but if you are on a budget this apartment is a good option.
