Location location location! We love Pijp, and this apartment is perfectly located steps from Pijp metro (< 30 mins to airport, similar or less to Amsterdam Centraale), the museums as well as the bars and restaurants of the neighbourhood.
The space is trendy, well designed and furnished (it is after all the hosts' home...) but be aware two of the bedrooms (and the open plan living space) open onto a busy street meaning plenty of noise if windows are open (closed, there is no problem).
Constanze and Boris are excellent and very welcoming hosts. A pleasure to interact with, just a shame Amsterdam prices for this kind of accommodation are so high.
