Everything as expected, location, flat etc. :)
We also came to Brussels kinda late (after midnight), but there were no problem for us to meet. Peaceful & pleasant experience.

The little boy is just around the corner (and in the mornings there are not that many people); keep it in mind that there are stairs(if you know you hate them you shouldn't stay there, otherwise it's fine); there is also book-store on the ground floor, unfortunately only Tintin book was in English there, though another second hand store was just a few more minutes further(second floor for English books).
