We stayed a whole week in Kristiaan's apartment in Antwerp. It was super clean and all necessary supplies in bathroom, kitchen and living/bedroom were there. The supermarket is within 5min walking distance so you can start cooking right away.
During our stay we travelled a lot through Flanders in general so the walking distance of 15-20min to the central station was one of the main criteria for us to choose this apartment as our homebase.
Communication and check-in with Kristiaan went very smoothly, he answered quickly and made sure to meet us at the apartment to show us everything.
He also supplied us with a lot of useful information about what to visit in the city and about the city's history. He has a great knowledge of details and funny stories about his hometown.
We really enjoyed our stay and can only recommend this apartment!
As described it's best suited for a couple but 3 good friends can manage to stay there as well.
