We lived at Frank's at Easter 2015 and we had a lovely stay. The apartment is really nice and Frank really made ​​much of the details. We felt very welcome and Frank had bought juice and croissants for us. Frank was flexible about our arrival and departure which was really nice. The only thing we would have liked was that the apartment was a little more clean. There was no clean dishcloths and tea towels in the kitchen and Frank had forgotten to take out the trash - but it was a small minus.
Jordaan is a super nice area with many small cafes, shops and restaurants. We can recommend Franks home if you want a nice relaxed stay in Amsterdam.
