Elmar and Michelle were the most gracious hosts we've encountered! We came in very late, but Michelle was waiting for us to ensure we got in and settled. Their roommate let my daughter borrower a sweatshirt (we didn't expect it to be chilly) and an umbrella (we didn't think about it raining!). They were very helpful in helping us know what subway to take, how to get places, etc. They had maps and instructions waiting for us in the apartment, and she already had the extra bed made out ready to sleep when we arrived. We couldn't have asked for better hosts! Would recommend them to anyone coming to DC!
