Jasper is a fantastic host - he's very friendly and immediately made me feel very welcome in his home. The apartment is exactly like the pictures, and is a great place to stay. You have several nearby by rail connections, and Jasper also lent me his bike (the bike was great, although biking around Amsterdam when you haven't biked in years can be intimidating!) He made sure to point out a nearby grocery store and cafe, and he was very responsive to any questions that I had. I would definitely recommend Jasper as a host!
