Everything was just great. 
Before we (my boyfriend and I) started the trip to Amsterdam Jeffrey and Petra were really nice. When I had a question ... they always sent a very quick response. And we got a very exact description from the way to the apartment so it was really easy to find.
The apartment is soooo nice and beautiful. It´s even better than on the pictures.
Petra gave us a very warm welcome and explained everything. They also had some chocolate and a bottle of wine prepared for us. 
The apartment is in a nice and quiet neighbourhood. And there is a tram- and bus station 2 minutes away.
But if you like to walk to the centre … this is also possible … and we did that the first day since we always like to explore the city. 
So all in all … a perfect place to stay if you go to Amsterdam.
