We had a great stay at Fabrice and Emeline's place. The neighbourhood is charming, very close to the centre, and getting to public transport was easy enough. The apartment was cozy, clean, thoughtfully furnished, and had everything we needed for our short stay. Fabrice and Emeline were always quick to respond to any queries or requests we had.
The only downside to our whole trip was my friend getting pickpocketed outside the nearest Metro station -- which is not the hosts' fault at all -- just something to keep in mind that some of the nearby surrounding areas are not that great and it's important to always be vigilant. Our hosts were very helpful in directing us to the nearest police station, even in the middle of the night.
Overall, would highly recommend and would want to stay with them if I'm ever in Brussels again.
