Overall a very cute, (relatively) affordable personal unit in DC and really great host!
I really liked the place! It's a small basement unit with extra amenities like a kitchenette and a washer/dryer unit. For the summer heat, the place is kept very cool inside, but I'm a bit sensitive to the cold. This was fine, though, because Chong provided two heaters inside the unit that were very effective. My one complaint is the location. I did some food deliveries and communicating the exact drop-off location was a bit difficult. Also, while the location is still close to downtown, it still takes ~ 20 - 30 min by bus/tram to get to Union Station and other places downtown. That being said, the public transport is very easy to access from the unit. Being a female solo traveller, though, I avoided staying out too late on the public transport.
There were a couple hiccups during my visit, but Chong was a very helpful and communicative host! I stayed in the summer, and I didn't expect the number of mosquitos DC has. Chong helped me out by lending me a bug lamp and an electric swatter that were very effective but if you're not vigilant about the front door, it's very easy for bugs to get in. Additionally, there was a power outtage one morning. Service came back that afternoon, but there was a smoke alarm in Chong's house that kept chirping after the power reset while he was out of town. However, we were able to fix that issue pretty quickly because Chong's neighbor helped out :)
