The place was overall clean and comfy, and in a great location; it would have been better with a few more items and a bit more cleaning.
It was easy to find and check-in, thanks to the comprehensive directions and 24h door attendant (we arrived several hours late due to flight delays). Check-out was easy, too.
The location was convenient, being a 10 minute walk from Union Station, next to a drug store (CVS?), right across the street from Whole Foods, and close to several restaurants and other businesses in that part of H Street. There's a back door that lets out into an alley onto G Street, which had much less traffic than H Street and was our favorite way to get walking to the Capitol area. They were installing Amazon delivery lockers while we were there.
The rooms were sparsely furnished, which was partly great. We've stayed in places before where there was no space to unpack and avoid mingling our stuff with the host's stuff. Here, though, there was plenty of counter space, drawer space, and closet space, and no random knick knacks to get in our way. A downside was that the kitchen was a little sparsely stocked, e.g., there were one small and one medium pan but not a large one; and there were no potholders and only one dishtowel (we ended up using some of the hand towels from the bathroom).
The rooms were clean where it counted most: the beds and bathrooms. The rooms had no musty smell, and the floor seemed clean. There were a few parts that were less clean, e.g., several things in the kitchen had been put away dirty, there were bits of food or something under the master bedroom dresser, and there were quite a few crumbs in the fold-out futon/couch.
The biggest downside were the blinds. We came from the East Coast and, due to jet lag, wanted to sleep in a bit. But in the evening, there were courtyard lights shining from early evening on, right outside the windows, and the bedrooms were basically fully lit by 6:30am (we visited in summer, when sunrise was before 6am). Curtains or some other way to darken the bedrooms would have greatly improved our stay.
