First let me say that Karl's place is beautiful. It is conveniently located near all the bars and clubs on U street and is not far from the airport (15 min), National Harbor or Georgetown (25 min drive each). We rented a car and noted that street parking was easy to find. It is clear that the neighborhood is going through a gentrification process, so at night just don't walk the street alone. Throughout the process and check-in Karl promptly responded to every email and question I had. However, there was an issue with the ac when we first arrived and eventually was able to get it fixed (Karl came out so we got to meet him which was cool). Other than that the house was great! It felt like home and had the cutest backyard!!
