Marc’s place was a great place for my stay in Brussels. The location is great, just a 4-minute walk to the Royal Art Museum and about a 10 or 12 minute walk to the central plaza. However, it is on a quiet street, away from the noisiest parts of the city. The unit is in the ground floor, so no stairs to walk up, but footsteps and conversations of people walking by will be audible if you have the windows open.
Check in was incredibly easy with the keys in a lockbox on the door. The apartment is a studio and somewhat small, but perfect for me, a solo traveler, or for a couple. Everything I needed was provided for, and Marc even let me check out a bit late at the last minute. I wish I could have stayed longer and would definitely stay here again.
