William was a very responsive host. We had a number of questions at the beginning. We were having a small family (5 people) reunion and it was helpful to have the space. The two architects (and the rest of us) appreciated the design and layout of the apartment as well as the iconic building with amazing views! The set up of the bedrooms necessitated a familiar and close family, since the loft offered little privacy in that part/section. Unlike airbnbs in the US there were few instructions and few rules. This felt open and welcoming. The only disappointment was the heating was inconsistent - though William did try to assess our concerns. If I visit Antwerp again with family I would happily stay there a second time.
