Patrick's place is super conveniently located. Everything is at a walkable distance—less than 10 minutes to the main shopping boulevards, 10-15 min. to the Grand Place and just 10-ish min. walk to the northern train station. Small supermarket (Carrefour express) is around the corner. Metro seemed also 5ish minutes away (didn't use but walk by the station). There's a couple of restaurants nearby and a huge selection of eateries 10-15 min. walk away.
The apartment is like the photos show—clean and cosy with a humongous bed in the middle. The windows look to the inner atrium which keeps the street noises away (so, don't expect a view). There is everything you need to cook some food. Patrick was nice to grant access to washing machine and dryer in the cellar, which was perfect as I stayed a full week with just a carry-on bag.
Overall, an ideal small flat to enjoy Brussels on foot.
