We arrived very late (after midnight), but we were able to reach Tarik via phone and text. There was definitely an element of trust in how we retrieved the keys and all that, so that was nice. Although we never met him in person, he seemed very nice and tried to see us in to the flat despite the lateness. The flat itself was nice and tidy, and nestled in a very nice (though touristy) area near Grand Place. There were a few towels prepared, and the sheets seemed clean. We're a bit independent, but had we asked for recommendations about Brussels, I'm sure he would have been happy to offer them. All in all, a very nice experience.
