Take Green line to U St. /Cardozo stop. Exit the Metro on the 10th St. /African American Civil War Memorial side. When you come off the escalator at street level, walk over to the CVS. You will be facing U St. at 10th. Cross U St., walk up 10th St., turn right on V St. and go half a block to 923 V. If you find yourself at the other exit (emerging near Starbucks), walk East on U St. (toward SunTrust), cross U at 10th St. and proceed as above.
