The best thing I liked about Messeret's place is it's proximity to metro DC plus it included a visitor off-street parking pass . Ubering from the Amtrak station was also very affordable for one of us since it was less than 2 miles away.
The snacks and drinks in the cupboards and fridge were very welcoming. The washer and dryer came in handy as well. I would definitely consider staying again if we're ever in DC again.
