We stayed at Rogier's property for two weeks with a family of 4 (including a 4 year old). The place is a nicely laid out modern Dutch house, well stocked and immediately feels like 'home'. The location is good - in the South not in the center of Rotterdam but 5-10 min bike ride over either Erasmus or Willem bridge (15-20 min bike ride to Centraal station/main shopping areas/etc) and also very convenient (easy short walking distance) to trams, supermarket, the Fenix Food Factory and other nice restaurants and places to go out locally.
The host was super helpful, welcoming, and responsive.
Very child-friendly too, the house as well as the neighborhood with multiple parks nearby, large and small, including one about 30 meters from the house at the corner in the neighborhood common area.
Definitely recommend for short or longer stays!
