If this place is available during your stay in the city, book it without think. Marjolijn and her partner are lovelly people. They were the best hosts I,ve already have using airbnb, always ready to have a good chat if you want and at the same time very respectful regarding your privacy. The house is simply amazing - provides much more than we usually need
during a journey. Besides the big and charming bedroom (wiht a good bed and a cozy balcony) you will have a private bathroom with hot shower and a bit infrastructure to have coffee and tea whenever you want with complete privacy. The location is perfect - in a charming and quite street really close to everything. I couldn't had have a better choice in Rotterdam. I highly recommend them as hosts and this place.
