Travis's place is in a great location, about 15 - 20 min walk from Union Station. We did a Big Bus tour (hop on/hop off) and got to see a lot and then spend time at the places we wanted to visit. A good way to get around. Most things are centrally located, easy to find.
We were out most days and dined at the local eateries, also great. Definitely try Match Box. For tired travellers, the apartment was beautifully quiet, we slept very well.
Would recommend Travis's place. Lovely neighbourhood, beautiful homes and street-scapes. Washington DC is well worth the visit and Travis's place is a great base.
