Nestled among quaint townhouses on a quiet side street a short walk from the Kennedy Center, Georgetown, the White House, and the Foggy Bottom Metro station, the River Inn is a comfortable refuge for all sorts except rabble-rousers. Most of the units in the all-suite property are studios, in which the bedroom and living room are combined; 33 units are one-bedrooms, which are roomier and include either a king-size bed or two double beds, as well as a second TV in the separate bedroom. All guest rooms provide a full kitchen, bed topped with pillowtop mattress, cushy armchair, a sophisticated decor, and a sleeper sofa. Upper-floor suites offer views of the Potomac River and two, nos. 702 and 802, catch sight of the Washington Monument. (These are always in demand, so seldom available.) Complimentary bikes (based on availability), on-site coin-operated laundry machines, a “stock-the-fridge” program that allows guests to have groceries waiting for them, and an especially gracious staff are among the pluses that keep the inn steeped in bookings from happy repeat customers.
