Fantastic location, across the street from Mannekin Pis and about a 2 block walk to the main square.  Easy commute from at least two train stations.
Numerous waffle, fries, and chocolate shops in spitting distance.  Although on a main pedestrian street, everything quieted down before 10pm and so I had no problems sleeping.
You do need to climb stairs to reach your room, so if you have mobility issues or extra large bags, this might not be for you.  I travel with a backpack so a non-issue.  Staff was very friendly and check-in was easy.  I arrived early and they held my bag until the room was ready.  
Room included hair dryer, soap, and shampoo.  (No conditioner, common in Europe.)  Room had a safe.  Room was clean, if slightly dated.
