It was very easy and fast to book, check in and check out of Greg's apartment thanks to him being constantly online. He replies fast with precise info about how to get there and how to live in his place and the four of us who stayed there had a great time. Dupont Circle is a fun and lively neighborhood of D.C, walking distance to all the monuments and museums we wanted to see. There even is a small back patio where to relax at the end of the day with a glass of wine. I do recommend this place.
