Sylvia was a great host. Good communication on check-in and checkout, gave me all the privacy I needed, and was quick to respond to any questions I had.
The place was very spacious and comfortable by DC standards, and the location was a fairly quiet residential street by DC standards (lots of townhomes nearby). I got my own designated off-street parking space, which is very convenient in DC. Short drive to all the downtown touristy stuff, but not much touristy stuff within walking distance, other than the Smithsonian Anacostia Community Museum.
I stayed there for about a month for work, and the one thing I didn't really like was the size of the mini-fridge and sink. Both were a little small if you're planning to eat meals at home. (And there was no stove/oven but there were some countertop-style appliances like an air fryer and a George Forman grill.)
