Daniel was away but Robert stood in and was readily available and helpful. Houseboat is in an excellent position close to shops and varied eateries. Inside it is well laid out and comprehensively equipped. We were only two but it would be fine for four or five good friends. We particularly liked the excellent new shower room and the unlimited hot water. Breakfast down by the water made for a special start to the day even when raining.
Would definitely consider when returning to Amsterdam.
