Patricia's home is a lovely and convenient place to stay for your trip to DC.
It's a converted basement in a residential part of town - so do be aware that you'll hear footsteps and general noise from neighbours. This was nothing unusual (no loud noises) and should be perfectly normal for a visitor with any experience living in a city!
Ubers from Patricia's place to the main sights in DC (Capitol / National Mall / museums) cost us about $7-$8 on average.
