Our stay at Jo's place was perfect. Her place is nice sized, clean and in a great location. (Make sure to check out the pretty view from her little balcony, overlooking one of the canals.)
Jo is a wonderful host. She makes sure to make you feel welcome, provides a manual with everything you need to know about her place and will answer any questions you might have. I definitely recommend staying at her place. If I get to visit Amsterdam again I'll stay there again for sure :)
