The appartment is in a quite central Washington D.C. location and has been exactly as described: modern, spacious and very clean.
We can generally recommend it if staying several days in this city.
However we had wished that Sara would be reachable via phone directly at check in time, since we had trouble getting the doors access code. Sara has sent it 1 day before check in time, however we had no internet access at that time, so we did not get the code in time.
