Location, location, location! And a clean, well-lighted room. That's what Matt's place is about.
The address is stellar for its proximity (1 block) to the train, bus, streetcar. You can walk to many wonderful Capitol Hill attractions and get downtown very quickly.
Bed and linens are good quality, and apparently laundered with unfragranced detergent, if that's important to you. The bed is on the cushy side. There are lovely can lights throughout. I didn't use the kitchenette, tv or pull-out couch. There is a nice closet with good hangers and an iron. (A long, or full-length, mirror would be a great addition.) Wifi works well.
The space could use better soundproofing from the floor above. I could hear phone calls and play Name That Tune when there was music playing. It wasn't super-loud, and it was quiet at night. But when there was sound, it was intrusive.
The bathroom, while clean, was sparse when it came to amenities. In the tub, there were a couple slivers of bath soap, worn down by previous users to the extent that I almost missed them. There was shampoo and conditioner, however. The bathroom design lacks towel bars and the hand-held shower head is 6.5 feet up, by my casual measurement. I'm 5'3" and could just reach it.
