I adore the host, Margareta, and this Antwerp apartment. I highly recommend this place.
The apartment itself is better than advertised. It is clear that so much thought and care have gone into this place; every day, I was discovering new things in the house to aid my trip. There is a fully stocked kitchen, dishwasher, large refrigerator, and this is the perfect place if you are staying in Antwerp for awhile. Everything is extremely clean. In my case, Margareta did a wonderful job of setting up the second bed (sofa bed). I have no complaints about the space.
The place remained warm even when the temperature outside was cold, I did not need to use heat at all. In the winter, you probably will need to do so, but there is heat in the main room and the bathroom. You will not have any issues here that make you uncomfortable, and if you do, Margareta will address them rapidly.
Location wise, if you are coming into Antwerp, it's actually a 16-minute walk from Berchem Station and a 21-minute walk from Centraal. It's about a 28-minute walk to the historic center. However, there are a couple of tram lines that meet right outside the house and can take you anywhere if you aren't up for the walk. The location is very safe, there are plenty of restaurants and a grocery store nearby, although be aware that many of these will be closed on Saturdays in observance of the Sabbath.
I selfishly want to leave this place a bad review to keep it to myself, but I cannot. The host was so charming and responsive to any questions that I had, I hope in a parallel universe that we are friends. If you are coming to Antwerp, you should absolutely stay here.
