Harrison's place is an affordable alternative for those looking for a place to stay near downtown DC. This was a good fit for me, because I'm a student who needed to interview at a nearby medical center (his place is 15-20 mins from most major medical centers in DC without traffic).
Harrison and his girlfriend were nice. The area itself isn't a great neighborhood but that being said, I also didn't feel unsafe (there are some sketchy parts in the surrounding area though). They had degenerating pumpkins from Halloween out that were rotting and smelled putrid (keep in mind this is after Thanksgiving). The living space itself was not very clean either, but the kitchen and living room area were pretty clean (big surprise). The kitchen was actually nice, but the microwave is missing a handle and made me have a wtf moment trying to figure out how to open it. I don't think the comforters I used were washed (they didn't wash or change them for the guests that came after me...), which is a little concerning. The room itself wasn't bad, but it was legitimately freezing. If you're the type to want a "homey" room, then I don't think this place is for you (I personally didn't mind). The bigger issue was the bathroom which was pretty dirty- hairs all over the place, garbage not changed, the red rings or Klebsiella in the shower and sink. I actually cleaned the bathroom for them because it was so gross.
All in all, the place isn't bad, but I wish there had been more cleaning done before I got there. If you are traveling alone and aren't picky, this place will work for you. It would have been a perfect stay for me of it wasn't so dingy and clean. He was a communicative host and was pretty accomodating. But some smells and stains are hard to get out of your memory.
