I had a very enjoyable stay at Marcelin's place. It is in a perfect location if you like art, antiques, and chocolate in the Petit Sablon and a great base to explore Brussels from. Marcelin was a gracious host who welcomed me and showed me around the apartment. The apartment has everything you need for a comfortable stay, even though it is an older building and not everything worked perfectly. It is plenty charming, though, and has a spectacular view over the roofs of the center of Brussels. As others have noted, it can get a bit noisy with bars and a church across the street, so ear plugs could be helpful. Thank you, Marcelin, for the stay. I would not hesitate to book again!
