This studio apartment was perfect for our three-day stay. The location is good: a very safe mostly residential neighborhood, shops and grocery across the street, metro a block and a half away, and the zoo a couple of blocks in the other direction. Traveling in and out of DC was also convenient, as Connecticut is a major avenue with easy access to freeways. The apartment had a nice, adequately supplied kitchen, a bathroom with a shower/tub and good skylight, and a main room with a comfortable king bed, several closets, a small table and two chairs. Somehow the apartment channels street sounds, but they were quiet and not a problem (there was a very faint beep, which we finally decided was the street crossing signal for the blind, and a somewhat boring guitar in the evening but not late). It was on the third floor, no elevator.
We had one unsettling thing happen. Someone unlocked the door and started to come in the second night we were there. I called the owner, who seemed dismissive, saying it was some kind of mistake. Still half asleep, I asked who would have a key, and he said it was probably the super. Maybe, but why didn't he know we were there, why didn't he knock if he didn't know, and why was he coming into the apartment at night?
Nonetheless, we'd stay there if it's available the next time we're in DC.
