Petra is a friendly and helpful host. She shared few shopping locations in detail to me after knowing my suitcase was broken and answered my questions patiently.
Her house is in a quiet neighbourhood with convenient location, it really closes to airport (1 station by NS train) and Amsterdam center (20 mins by bus 18). The apartment was clean and tidy, looked exactly the same as every photo.
Just one thing to remind, you have to climb up a pretty steep but short stair in order to reach your flat. So, make sure you do not have heavy luggage unless you are not travel alone.
