What can I say about Mark's apartment? Well, it was wonderful!!! I only stayed for one nite, but I will definitely be back. Great location between Foggy Bottom and Dupont. And the apartment itself is brand new and beautifully decorated. And clean! Great security and easy to access keys. Mark was quick to communicate and answer questions.
In an effort to leave some constructive feedback - I was traveling on Biz, so a desk and desk chair would be a nice addition. Would this keep me from staying here again? Nope.
