Overall it was a very comfortable and pleasant stay. The place was decorated to its true theme (Industrial). The beds and sheets are very comfy, which is essential for traveling. For 4 of us, the place is definitely a great fit. But for 6 or 8 people, staying in the living/family room together could be a bit tight.
A minor comment regarding the missing provision of soap in the soap dispenser in the master bedroom and coffee pods in the kitchen. They did provide two soaps so it was fine. We are not big coffee drinker so that's also fine with us.
To get to the apartment, you need to climb stairs so for people who have weaker knees, may want to take a note of that. But the place is really comfy and stylish. We love the smart lock idea, as we don't need to worry about losing keys!
Justin is very responsive throughout. The location of the place is good. We used Justin's guide and went to the DCSmokehouse nearby and it was SOOO GOOD. Thanks for the tips.
