Would highly recommend staying. The apartment had plenty of space for us as a couple, and was clean and had a few essentials provided, which was very useful after a long flight. The metro cards were also really handy, and there are a couple of bus stops only a few minutes walk away
We met Jon as we arrived at the apartment, and he was very friendly and helpful. Jen was likewise quick to reply to any questions and messages. The information they provided helped make our time in Washington a lot of fun, and we'd certainly stay again!
