Margot and Daniel’s place was great, they were very responsive, and they were even able to work out giving us a later check out time, which allowed us to leave our bags at the apartment while we did one last day of sightseeing.
The only drawbacks are that it’s a bit noisy with the family upstairs, and you don’t have access to a thermostat. In our instance it was really muggy in the basement apartment the whole time.
I would definitely recommend their place for tourists, an Uber was typically $12-$13 to the National Mall, and the apartment is in a quiet part of DC right next to a beautiful park!
