There are a some things to understand about DC right now. First, most people aren't back in the office including the government so it may be a little bit dead around K street, especially at night. Second, DC is aggressive with masking policy so expect to deal with that. I would look at a map to get your bearing. You are four blocks from the White House south and four blocks from Dupont Circle the other direction. When you look at the map, it can be deceiving. You are over 2 miles by foot to the Capitol. Just make sure you understand how much walking is involved. Uber and Lyft are your friends.
