We stayed 6 nights at the end of March. We were attending a 3 day conference at the Woodley Marriott and took some extra time to tour DC. The apartment was a great place for our needs. It was very quiet, which assured a good night's sleep. We enjoyed having the kitchen to make coffee and continental breakfast, with coffee and breakfast items provided by the owner.
The location is close to restaurants and very convenient to the metro. The owners were very cordial and included a booklet with tips on restaurants, etc. We would definitely stay here again when in the area.
