AMAZINGLY located- basically everything you'd want to see/need is veeeery accessible by foot. Grand Place, Palace, Mont d'Art/museums, grocery store, and night shops are all within a 2-10 min walk, tops. Sablon district is just outside of the Grand Place crowds, so nights are relatively quiet.
Max's place is even better than described. To be considered "cozy", it is suprisingly spacious . Great ceilings, fully-stocked kitchen, and very comfortable bed and sofa! One small thing- the bathroom is essentially in the kitchen and efficieny-sized with a sliding privacy door, but considering the incredible historic building/rest of the space/value this didn't bother me at all.
Max himself is an incredible host. Responsive, informative, and just generally gracious all around. Totally exemplary! Would definitely stay here again.
