I came to Amsterdam for the marathon and stayed at Janwillem’s place for a long weekend. It was a perfect base, beautifully decorated and very comfortable. I hired a bike from the place just round the corner (GARILEO BIKES RENTAL & TOURS, https://goo.gl/maps/AssXeegNUuKjwDjD7), which I highly recommend for getting around, although bus and tram stops are also close by.
Would definitely return.
