Alan is probably the best host one could wish for. He enabled early-check-in and provided us with a useful map with supermarkets, drug stores and public transport that are all within short walking distance (5 min), some restaurants and bars are around the corner. Taxi from Union Station to the apartment is less than $15 Dollars. The apartment was very clean. We stayed 2 nights with 4 people in the apartment and had a great time. However, for longer stays in D.C., the apartment might be a bit too small to accomodate 4 adults.
