I stayed at Nicholas' place for an extended period and it was fantastic!
The apartment is located in a residential area with easy access to grocery shops, a great gym, parks, public transport and just about anything else you may need.
The place itself is huge and well decorated with high ceilings and lots of natural light.
Nicholas was always helpful and fast to respond to and questions I had.
Based on my experience with other places in and around Brussels, this stands out as exceptional.
