We really enjoyed our stay at Natasja's and Mylan's. The appartement is very well located (5 min walk from the Central Station), so we could visit Rotterdam and go to The Hague, Delft, Dordrecht and Amsterdam very easily. The noise from the street was not a problem at all. Communication was really easy with Natasja, we got all the informations needed before our arrival, and she was reactive to every question we had. Besides, our return train being at 5pm, she offered to store our luggage in another room so we could enjoy our last day in the city without carrying our suitcase, which was really appreciated. Maybe one thing to improve: floor and furnitures were quite dusty. Otherwise, we recommand the studio for sure!
