D.C. is a great city for walking, and this location is the place to begin. The Mall, Capitol, Supreme Court and the Library of Congress are nearby. Even so, this location has a neighborhood feel, and there are several wonderful green spaces across the street and down the block. There are also a variety of restaurants close by. If you are staying for a while, there are two gyms nearby.
The Metro is a mere 1 1/2 block away. The elevator for the Metro is straight down the street, which is nice for people with strollers, crutches, etc. or other people who might have difficulty when the escalators to the Metro platform aren't working or are under repair. You can get to or near many of the places D.C. is famous for, as well as to some excellent restaurants and theaters. If you like farmers' markets, be sure to check out the one at Dupont Circle on Sundays or the one at Eastern Market on both Saturday and Sunday. Both are right next to Metro stations.
If you choose to eat in, the apartment has all the appliances you need---there are two grocery stores within walking distance (if you like to walk!) or a short Uber trip away. The elevator for the Metro is straight down the street, which is nice for people with strollers, crutches, etc. or other people who might have difficulty when the escalators to the Metro platform aren't working or are under repair.
The apartment is an English basement and very sunny. It's clean and organized---the bed is very comfortable. It was great to have access to a washer and dryer (convection). The location is reasonably quiet at night, considering it's in a city. Juli arranged for a visitor's parking pass during my stay, and I did not have any difficulty finding a parking space nearby, regardless of the time of day.
Check in was seamless, and Juli was very responsive from the very beginning of the reservation process. I really enjoyed staying here.
