I Loved this appartment. If you're considering to book it, please have in mind that is just for two people. The location is amazing, you're literally at the city center and you're minutes walk from a lot of places like the manneken pis, the grand place, Bruxelles centraal station and the metro.
You can get a early check inn, our you can leave your luggage at 1 pm, that really helped us a lot.
I would definitely stay there again!
