We had a wonderful stay at Onno and Christiaan’s place. Onno greeted us on arrival and gave us a tour of the apartment which was wonderful. The apartment is in a great location and very close to public transport. Onno was very quick to respond to our questions and even let us check out late because we had a late flight! As others have mentioned, the stairs are very narrow but we didn’t find this to be an issue. Highly recommend!
