Pluses: very quiet (the inn was full and we never heard any noise at all), wonderful location (walk to metro, numerous restaurants and shops), good breakfast, beautiful common rooms, very comfortable bed and first class linens, free Wi-Fi and newspaper, plenty of room on the bathroom counter. We stayed in the Mosley room (3rd floor in back) No noise at all from outside. Joanna was very friendly, and made us a "to go" breakfast when we had to leave early to catch our plane.
Minuses: Upstairs could use a little TLC-patch and paint. My in-laws were on the second floor (in the front) - that room was in better shape. Parking is extremely limited - and if you have to park off site, you must walk. I understand, this is D.C., but be forewarned. Breakfast is only served for a limited time, and on the weekends that is 9-10. I like to get going before then. overall a great stay, we would definitely go back (especially because this is the closest hotel to Mt. Pleasant, where our daughter lives)
