Sietske is a helpful and amazing host. She gave great tips, and she truly knows the city like the back of her hand. Her houseboat is also amazing and conviniently located as well. Her houseboat is all her doing, as she has reconfigured a ship from the bottom up. The entire place shows she has poured her heart and soul into it. If you have a chance to stay here, do it. You will not regret it.
