Diana is a lovely person, an excellent host and her great apartment in a desirable neighbourhood had more than everything we needed for our 7 night stay. Public transport, food stalls, cafes and restaurants were available at nearby Eastern Market (closed Monday). Capitol Hill supermarket is a couple of minutes away, and although small, it stocked everything we needed, eg, unsweetened soya milk and no added sugar muesli.
The apartment is a short walk from the Thomas Jefferson Building.
Diana's apartment is highly recommended.
