We stayed at this place for three nights in April. Very nice private flat with a kitchen and bathroom, there's also a beautiful garden with a cozy terrace.
The house's location is great, about 100 meters from the tram stop and the metro station, main museums are in a walking distance.
Kees and Marjolijn are very kind people, it was a pleasure to visit them.
If you're​ going to Rotterdam, this offer is probably the best way to stay in this wonderful city.
