My friends and I, stayed in Sarah's place just one night, and it's our regret that we planned such a short vacation in Brussels, because we really liked both, the nice and very cozy apartment and stunning city as well.
The place is very clean, warm and comfortable for a longer stay (there is good kitchen and family table). The location is great, the bus station is right in front of the building, it takes less 20 min to get to the city center.
Highly recommend!
