The apartment was as described, however, we were not happy with the neighborhood and apartment building. There was a constant pungent, irritating, smoke type stink in the hallways and building. Thankfully it was not inside the apartment, so we were able to complete our stay. While the DC area overall seems safe to walk around (we dined out late in the Georgetown area), this neighborhood did not look safe after sunset. We had to get gas and ventured out to the closest gas station but never advise anyone to do the same.
Kina was generally responsive to messages I sent and clarified some of the incorrect check-out related automated messages I received. The check-in pictures and instructions were slightly complicated but very helpful. Note that Google Maps takes you to a slightly different location than the actual building, so consulting the pictures was helpful.
