We really enjoyed our stay- the apartment was nice, clean and spacious and had everything we needed. The balcony was lovely for morning/evening but hot during the day (as expected for summer in DC). Cristopher arranged a parking pass for our car and the apt is very close to the metro, which we used for most of our sightseeing. There is street noise and plenty of sirens, but again, what you'd expect for DC/any big city. We would definitely stay here again.
