I stayed at The Blue Courtyard for a week and it was lovely. 5 stars.
Marc responds very quickly every time which made me feel comfortable and safe. I moved my check-in date one day early on two-day notice and Marc was very nice about it. When I checked in, it was his birthday and even then he still entertained my questions and gave very clear instructions on how to check-in. He is an amazing and very accommodating host.
I enjoyed my stay and recommend this place to anyone considering visiting Brussels. Although the location is not in the city centre, there are many ways of public transportation near the apartment. A couple of friends have told me about the dangers of Schaerbeek, this particular area of Schaerbeek is quiet and safe in my experience. Furthermore, a 2-minute walk to ALDI down the road makes it comfortable to buy groceries. In the apartment, I didn't feel like the heating was strong enough but the place provided very nice beds, a clean bathroom and tourist guides.
