Dan great well welcomed us. He is hyper organized : easily available key on arrival even if he is absent (it was not the case for us), a recapitulative index paper with all the practical points waits for us in our room: subway, buses, restaurants, supermarkets, everything is there!!! He is also available to answer the questions and express his opinion on the museums which we wish to visit. The room and the bathroom are very clean and it is nice to discover a typically American house. We spent a very good moment in Washington.
