We had a wonderful experience staying with Hendrik and Betty! Betty was very welcoming when we arrived, and had the apartment in perfect shape and fully stocked with snacks and drinks for us. She even let us check out pretty late the next day so could see Rotterdam before heading to The Hague. We were traveling with two bikes and it was easy to put them inside. The apartment itself is every roomy while still being cozy and welcoming - we only wish we could've stayed longer!
