My husband and I stayed in this apartment for a little over a month during a transition back to the US after living overseas. We thoroughly enjoyed staying here, and it's an extremely comfortable, homey apartment with everything you could need for a short or longer stay. Nice little kitchen with all the basics you need for cooking and eating at home, TV, cable, good wifi, a very effective a/c unit, great closet space, a comfy bed, and a washer/dryer - all the amenities are great. Plus it's just a nice space, and we were very comfortable there. The location is great - a little walk to metro stations but not far, and right off the lovely Lincoln Park (we used to live right in the neighborhood so we know it well and love it). We highly recommend the apartment for a DC visit!
Of course, Dick himself is really the icing on the cake for this place, as others have said. He's just a lovely man and a wonderful host, and we so appreciated his attentiveness - he checked in regularly to see if we needed anything restocked (although we would have also been totally okay just taking care of that ourselves), and when we were looking for another few weeks of temporary housing at the end of our reservation period, he even looked into some options for us unprompted - it was such a nice gesture, we really appreciated it.
In short, this is an excellent AirBnB option at a great value, with a delight of a host - don't hesitate to book it!
