David was very prompt at replying to queries by email in the lead up to the stay and during the stay itself. The apartment was very clean, beautifully decorated and very comfortable. Situated in a pleasant suburban area, the apartment is close to Union Station (for all major transport connections) and within easy walking distance of the main sightseeing attractions. The electronic entry system makes things very simple, and removed any issues of meeting the hosts to collect keys. We only stayed for 2 nights but wish we could've stayed for more. We would thoroughly recommend David and this apartment to anyone visiting Washington!
