We stayed for 2 weeks to get a feel for living in Amsterdam as we consider our upcoming relocation and Pim's place certainly allowed us to do all that and more. It's a great, industrial-type loft apartment located in a fantastically local neighborhood, but with just the right amount of retail and restaurants around the corner.
Also it has the benefit of being very close to Vondelpark for morning jogs or just lazing around the park taking in the scenery. Also conveniently close to the city center by bike or tram, so you'll definitely feel away from the craziness but 100% part of the city.
Finally, if you're a cook--or plan to cook while you're renting here, I will say this is THE best kitchen I've ever seen in Amsterdam -- or anywhere in a European Air BnB for that matter (most are the size of a postage stamps with no prep space or severely lacking in cooking accessories). Pim's kitchen is a cook's dream. Everything you can possibly imagine (from woks to juicers) is there and there's a ton of ethnic and organic grocery stores in the nearby vicinity. You'll feel like you haven't left your kitchen at home.
Finally, as others have said, Pim is a fantastic host--always around for any minor question you may have--he'll never make you feel like a bother. Definitely a 5 star stay!
