Christian's small apartment is very convenient and beautiful, near the metro station and other public transportation. It's in the downtown of Brussels, so you can explore the whole city on your feet. The apartment is very tidy and cozy. And Christian is easy-going and considerate. The only problem is that you may need to communicate with him to decide the check-in and check-out schedule. But I think it's still a wise choice to be his guest if you are a solo traveler and willing to explore the city.
