My wife and I stayed here for a week while I was visiting Antwerp for business. I wanted somewhere that she would feel safe and comfortable during the day while I was at my company's office, plus easy to walk to nearby restaurants, shopping, and tourist sites. This place fit the bill for us exactly being right in the town center - only 2 blocks from the Grote Markt, Groenplaats, & Cathedral and 4 blocks from the Meir shopping area.
The inside was very well laid out - more than enough space for 2 people - and had everything we needed including very fast internet, extended cable TV, comfortable bed & seating area, and fully equipped kitchen. Although with literally hundreds of restaurants and bars within walking distance, we actually never used the kitchen!
The parking space available (for a reasonable add-on) in a nearby garage works out great if you need it, as otherwise the parking would be very challenging. But if you don't plan to have a car, the place if very easy to get to by public transport from the Antwerpen main train station.
The host was always very clear in directions, procedure for getting access, checking out, and available by text or phone during the week for some occasional questions and recommendations.

Antwerp is a wonderful city and this is a highly recommended place to stay for any visitor!
