Everything about Patrick's place was great. The location was perfect. We didn't rent a car (though there is a parking space for one), but the apartment was only a ~10 min walk to the nearest metro station and from there you can easily get to the Smithsonian or anywhere else in the city. There is a wonderful coffee shop just around the corner. It was really hot in DC when we were there and the apartment was a welcome respite from the heat. The place was super clean, and the décor is unique and fun. Patrick was very responsive to my messages.
