We didnt met Anna and Marnix because they were traveling but Carline their friend received us. She explained everything and also Anna and Marnix let us maps and also a letter describing everything that we could need since the boat time and what was near to know... The appartment its way better then its shown in the pictures, we were really satisfied with it. Our time in Amsterdam was really good and the appartment makes part of it! I recommend Anna&Marnix appartment.
