Joost was a great host - after I mistakenly booked incorrect dates he did everything he could to help, including letting us leave our luggage with him when we didn't have anywhere to stay. The apartment itself was in a great neighbourhood, only 5 mins ride to Vondelpark and his friendly neighbours rent bikes for cheap. Inside it had all the mod cons and a nice back courtyard. The apartment can fit 4 people comfortably if you don't mind sleeping on a mattress on the floor - provided by Joost of course. Overall I wouldn't hesitate to stay there again and would recommend it for anyone who wants to stay out of the chaotic centre of Amsterdam.
