Adam's apartment is very conveniently located for the metro and all the main sights of Washington DC. Everything is within walking distance.
The apartment is very well equipped, smart and elegant. I stayed with my teenaged son, but it is large enough for a family of four with teenagers. It has been child-proofed and would be great also for a family with young children. And if you want a romantic hideaway, then this would be perfect.
I cannot recommend Adam's apartment highly enough. Stop reading reviews and reserve it now! You will not regret the decision!
