Catherine's place is as beautiful as it looks in the photo. It is very well-designed, very clean and all the basics for a very comfortable stay is there. The design is clean & minimal, so if you're looking for a "more decorated" place, this might seem spartan to you. For me, it was perfect.
As for location, it was convenient to public transportation and easy to get to places on foot. Although I go to Antwerp for work and have been there multiple times, so this comment is on the places I need to get to and not necessary "tourist spots".
I would certainly book Catherine's place again!
