Fantastic place! Location-wise, it's a quiet, pretty neighborhood half a block from a laundromat and the 14 bus goes straight down to the National Mall (within 2-3 blocks, anyway). The apartment is very clean and comfortable, and there is free on-street parking. Would definitely stay again!
Two things to take note of: 1) The shower is very compact. And 2) There is a decent amount of noise from upstairs, particularly in the morning. Neither of these notes are complaints by any means(!), just things you might want to be aware of if you're planning on staying here.
