You will not stay in a more beautiful location or as unique a residence as Roel's windmill and nor will you stay with a more charming and friendly host. We had a super 5 days stay in Amsterdam and we found it easiest to use the 17 tram in and out of town, which you can get to in an easy and pretty 10-15 minute walk. Panther the cat was as friendly and characterful as a cat can be.
In short it is a delightful place to stay.
