Caspar was very accommodating during our two-night stay, even nice enough to leave a little treat for my child. Though we never met him in person, his downstairs neighbor was very helpful, and his apartment is indeed very pleasant in an authentic, non-touristy but close to the center area. The only downside was a mosquito that got inside our mosquito net the first night but that was our bad luck and they are bothersome anywhere in Amsterdam with the kind of warm weather we enjoyed, at least he provides you with a "weapon" to defend yourself. I would recommend it for anyone who seeks independence during their holidays.
