This was one of the best Airbnb experience we had (especially after two bad ones). There are many great things about John and Ceca's place. Firstly, the location is fantastic. Super close to Grand Place, close to many restaurants and walkable to public transport. Apartment is very clean and had everything we needed for a comfortable stay. John provided very clear instructions and made it easy for us to check in and check out. John and Ceca make you feel welcome with complimentary water and cookies.
I recommend trying out the Istanbul restaurant that's just below the apartment. Their food was really good for the price they charge. Also try Moeder Limbac and Le Fin De Siecle.
