Convenient, depends on which wing you stay in
I think there is at least 3 major wings of this large hotel. One is the newer end which I prefer, the other two are a little unusual. Probably the original older section is interesting because of the room features; you feel like it was back in the 60s. Didn't check, but windows felt really cold in the winter, probably not noticeable in the summer. The other wing is actually floors below the main hotel. Hallways are freezing, but the rooms are fine. Easy to get lost in this hotel. Stayed here for a convention, and the Metro stop is right down the street which makes it very convenient to get to the capitol. A lot of local restaurants to choose from within walking distance, and even more restaurants a little longer walk down Connecticut Avenue. DC Zoo is also within walking distance even with kids.
