The posted description and photos are accurate, I would rent this apartment again. The past guest comments about the stairs are also accurate, the multiple levels of stairs are a challenge (especially with luggage). Location, Location, Location - you are right in the thick of things and very close to Grand Place. Close to restaurants and a grocery store. I stayed over on a Friday and Saturday and there was a lot of street noise, not super horrible but you will notice it. Super easy check in / check out process. Owner recommendation of Nanny bag was spot on ! Luckily, there is a Nanny bag location just doors from the apartment which made it super simple.
The Bourse/Beurs Metro 3 or 4 stop is walkable, even with luggage. I purchased a 10 journey MOBIB card for $19 Euros. We were able to share this single card between 2 people One of my favorite places not far from the apartment was Aux Merveilleux de Fred - Rue du Marché Aux Herbes !! EVERYTHING I had from Aux Merveilleux was soooooooo GOOD !!! Pizza Pronto was also very tasty. Café Capitale - Rue du Midi was good. The Wash Club was the cleanest laundromat I have ever been in. Word to the wise, don't pick wash cycle # 5 - unless you have 65 mins to burn !
