We rented both of Klaartje's apartments for our four night stay in Antwerp for our family and friend (two couples and a single) and had a wonderful time. The apartments are beautiful and modern, and very clean. We had everything we needed in terms of amenities in the apartment, and in the close surrounding area there is a great cheese shop, deli, supermarket, Panos quick pastry shop and laundry, among others. When we were there there was a transit strike so we really appreciate how well located Klaartje's place was to almost everything we wanted to do, museums, restaurants and the train station were walking distance or a very short cab ride. Klaartje herself is awesome. We had an issue with our originally planned accommodation, and I contacted her the afternoon we arrived. She offered to have us come over immediately to drop off our luggage while she cleaned following the guests who had just departed. She couldn't have been nicer. For those travelling with a smaller group, each apartment is separate and private and can be locked. For us using both, it was very easy to move between apartments so we could be one group when we wanted to be. I highly recommend Klaartje's place.
