We enjoyed being in a neighborhood place, with lots of people walking by. The unit is just a couple blocks away from restaurants and bakeries (yumm!), and our Uber driver found it no problem.
The two bedrooms are a nice touch, but know that the 2nd bedroom is downstairs down a very narrow spiral staircase, and the internet doesn't work down there. Also, parking is very tough, so not recommended to drive a car there.
I'd recommend the place as a base for seeing things in Brussels.
