Just stayed here for a trip into DC. A 30 minute drive if no traffic.
Very clean, and nice suites.
Nice location, indoor pool (shared with Embassy Suites next door), and very good hot breakfast.
The staff could have been friendlier however. The lady who checked us in was nice but no one went out of there way to say hi etc. When checking out, the man sat on his stool and asked room number and said okay. No thanks for staying, how were things, etc. Its not a big deal but these little things are what set this hotel from others like the residence inn down the street.
Only other minor complaint was no coffee in lobby 24 hours a day like most hotels.
