We arrived on Saturday and Denise was out of Washington, but Glenn met us very friendly and explained how to get to the apartment as well as provided the keys and metro cards.
The apartment was unbelievably cosy and comfortable, everything was ready for out stay and also the most friendly cat in the world welcomed us.
Denise came only on Monday, but appeared very friendly and kind. Everything is great with this apartment (except for the location: it's very faraway from metro, but there is a bus right on the corner that takes you right to the subway station), so we would highly recommend it to everyone who dreams about a good (and "feel-at-home") stay in DC.
