Summer housing in Washington is very hard to come by, particularly if you wait until the last minute.
George Washington University:
Your first stop should be George Washington University. If you are a member of the Greek community, check with your fraternity/sorority houses for availability on GW's campus. Otherwise, we suggest applying for housing in New Hall. It's just one block from the Foggy Bottom Metro Stop (very important in the summertime!), and has a range of rooms, all of which include kitchens. New Hall has doubles and quads from $252 to $259 per week, per person. All buildings are staffed with student assistants, who are on call 24 hours a day, 7 days a week.
Book your living space as soon as possible! George Washington is a convenient spot for summer interns and fills up quickly. Apply here.
Temporary housing for women aged 18 through 34, newly arriving in the city to work or study. TMH is located on Capitol Hill (235 2nd St. NE) within walking distance of Congressional offices, many government agencies, the Library of Congress, and the Smithsonian museums. It is also convenient to the bus and Metro lines and Union Station. Rooms are small but air conditioned, and monthly rent is a very reasonable $900 which includes breakfast and dinner Monday through Saturday and Sunday brunch.
Other options include schools like Georgetown and American University. Georgetown is very pretty but is too far from most of your internships to walk and lacks a Metro station, so you will have to use the bus system to get around. American University is in a nearby suburb; students who have stayed there liked it but did not feel that they got the full experience of living in Washington. Subletting options can also be found on Craigslist, which of course, should be navigated with caution.
