We had a lovely five-night stay here. It was our first trip to Washington and we wanted a place that was central. We also wanted an apartment so that we wouldn't feel too cramped and would have the option of cooking for ourselves.
The neighbourhood is great and we were able to park right on the street outside. The building is very quiet (we never saw the other residents) and safe. We were able to walk to almost all of the major sights, but you can also walk to the Eastern Market (10 minutes) and take the Metro from there. On foot to the Capitol is about 15 minutes.
The apartment is on two levels, with adequate space. Well-equipped kitchen and a very functional bathroom.
We were very happy with the choice. The cost seemed comparable to other options we looked at - not 'cheap' but not completely outrageous either.
An enjoyable stay - we would consider this apartment again were we to visit again.
