We lived in Alex's place. It's a farm with sheep and two cute dogs. We got some problems with the taxi driver. Be sure the place you go is 51 in Amsterdam. Actually there are two places with the same name. Alex did a great help to us to solving the problem. Really appreciate that. And at the last day, Henk took us to the central station with only 15 euros. Highly recommended this place. They are nice guys, trust me.
