I visited Brussels for the first time for Tomorrowland and I had a wonderful stay at the Airbnb. The Airbnb is located adjacent to a bar, and the bartenders are always there to help you out with everything. The location is priceless. You are minutes away from the Grand Place and every other major site in Brussels. The friendly bartenders make you feel like home. You will definitely feel like one of the locals. The apartment is well stocked with everything you need.
My only suggestion is if you’re a light sleeper, you may encounter some problems with noise since it is right next to a bar. The apartment is also fairly small, so will also hear every footstep from the people living above you. And lastly, the WiFi was a little weak when we were in town. But if you walk around the corner to the bar, you can catch the WiFi pretty easily.
The pros definitely outweighed the cons by a mile and I will definitely be back.
