We have stayed in many Airbnb places over the years and David is definitely the best host that we have experienced. He responded quickly to every email and text request or question that we sent. We were very impressed by his professionalism and responsiveness.
The house matches the description very well, it has a fresh, modern, clean feel to it and is extremely well equipped as a rental. It was fully stocked with laundry detergent, dryer sheets, soap, toilet paper, dishwash detergent etc. He had even provided full sized and compact umbrellas! We were able to cook in several nights for our large group of 8, and hang out playing cards and watching tv. Beds were comfortable, and my kids thought that the towels came from a spa! As the listing points out, the main house has three double bedrooms and the downstairs unit has an additonal two bedrooms. The downstairs unit is not connected internally to the main house, so people use the stairs to the front door to access the main house. No big deal but might need consideration if you have a house full of young kids etc.
The location of the house suited us very well. We were about a 20 minute walk to the Capitol end of the mall and Museums. We used Uber to get down to the White House and Jefferson Memorial since it was a bit further to go with the kids. There is a large supermarket and a Whole Foods two blocks away, and a great Indian restaurant is also in the neighborhood. David provided a very detailed list of restaurant options both in the neighborhood and for the greater DC area.
