I stayed at Sonder the Quincy for the weekend I had to attend a special event at one of the embassies in DC. I was delighted with the location, ease of check-in, and design of the room. My room was incredibly spacious, and I enjoy the fact that it had a kitchenette, Bluetooth radio in the bathroom, and multiple streaming options for TV. My only gripes were the fact that there was construction next door, so there was some noise. There is no front desk, but I think it would be a good option to have physical room keys as well. At one point my phone died and I had to wait to go back to the room as I had not memorized my code, and could not use my key. Aside from that, a great stay.
