I stayed with my family at Lisa's place and we had a really great time. It's around 3 miles form the National Mall area, so we took a Lyft/Uber every morning. The area is safe and the metro stop is just a couple of blocks away, so that's an option as well. The apartment is really modern and exactly as per the photos. The host was prompt in replying to whatever questions we had. The kitchen was very well stocked and had everything that you could ask for as a tourist. The host also provided some useful things such as an umbrella, extension chords etc. which were a great help. Overall, I would highly recommend this place for any group of 4 people who are looking for affordable accommodation in DC.
