We had a fantastic holiday on Dennis's houseboat! The previous reviews say it all but I just want to add the highlights for us were: great communication and very warm welcome from Dennis and his friend Kwame, very clean and super facilities (coffee machine is superb!), very comfortable livingroom with amazing views over the Amstel, hotel, and boats. If you have kids then they will love it. My daughter had a great time on the wee boat and even managed to catch a fish (returned to the river promptly!). We will book again.
