Roel was great. Not only did he accept our reservation on very short notice but he was also very nice, easy to talk with and friendly.
When we arrived he explained to us what is favorite places in Amsterdam were, and how to get there. Quite cool for tourists like us to be able to discover new things and not only the ones in the guidebook.
Plus the appartment looks even better in reality than in the pictures. It does have a very great view and is well equipped, everything you need for a holliday stay.
In summary, Roel is a very welcoming host, is appartment is great and you should book it without hesitation.
