Grace is an excellent hostess - not only very accommodating and helpful, but also quite personable (enjoyed chatting on various topics of mutual interest) without being intrusive.
The residence is extremely convenient; literally just over a block away from metro, and easy walking distance to grocery shopping.
The room was comfortable, the kitchen very convenient, and the common area (and TV/NetFlix) great for relaxing and downtime.
Great place to stay in DC, highly recommended.
