We spent a wonderful long weekend at Grégory's place. It was very good located being easy to reach the centre in 10 min and other attractions (atomium, sacre coeur, horta's museum, etc) easily reachable by metro or tran.
What I most appreciated is that Grégory was available anytime, gave thoughtful tips and also was very kind by picking us up from the station as we arrived and taking care of our luggage. I would totally recommend staying by Grégory's and will repeat when I come back!
Cheers!
