Jim and Kat's place is in a great location, quiet neighborhood about 5 minutes walk to the Capitol with nearby park, rows of restaurant and a short uber ride to the national mall. We really enjoy our time there. The apartment is very clean and well furnished with everything you would need. Our favorite is the massive tub and rain shower head. You could hear the water and flushing quite loudly if you are laying in the bed in the next room but that didn't bother us much since we tend to go to bed at the same time.
Check in was a breeze and Jim and Kat was very responsive to all of our questions. Parking was easy to find in the neighborhood. The wine was a nice touch :) We would definitely stay at Jim and Kat's place again.
