Are you in DC for a long-weekend? Sonder on Potomac is a great place, 1) clean and comfortable place, 2) so many options for food, 3) history is within healthy walking distance, 4) so close to amenities, such as a nice market, 5) so close to water-front without noise, and 6) very affordable!! If I visit DC again, I’ll stay at Callisto, Sonder.
