Although we had a litlle time to get to know Jan better he was really helpful and accomodating person. His appartment was great, very well situated for our purposes, at quiet location, 15 min to Central station and 15 min to RAI center. The appartment is very bright and neat with all equipment for a shorter or longer stay. I can higly reccomend it and would book it again without any hesitation in the case of the another journey to Amsterdam.
