This place is perfect for a short stay in Brussels. It is right beside the US Embassy and opposite the Turkish Embassy, so there is police patrol all the time and you feel safe. The apartment is a short walk from Arts-Loi Metro station, walking here with luggages shouldn't be difficult as there are elevators and flat roads.
The apartment is exactly as described and comfortable for a family of 4. The kitchen is spacious and well-equipped for cooking. The beds are comfortable, if you have someone willing to sleep on the top bunk of the bed in one of the bedrooms. The second toilet is very small but functional otherwise.
Our host Kuros has been friendly and responsive, making our stay extremely comfortable. Highly recommend!
