Me and my mom stayed in Brussels for 2 nights at Leo's house and it was amazing. The house was very very clean and so the bathroom/toillet and bedroom. He provided us a map with instructions about the metro and tram to the center and was very helpful at the checkin time. The location is between the center and the Atomium in a nice neighborhood: we came back home every night and we felt safe walking from de metro station to Leo's house.
I recommend it to everyone who's looking to spend some days in Brussels in a cozy room without spending a lot of money.
