There is no contactless system upon arrival. This means it would be nice to let Xsjong know beforehand if your flight arrives during regular sleep hours (late at night or very early morning).
Schiphol (Amsterdam airport) is currently (2022) a disaster and changes of your arrival might be unpredictable, but good communication with the host helps a lot :)
Keep in mind the apartment is quite away from the main attractions, and the last bus is around midnight (00:30 - 1:30 or so). If you come to Amsterdam just to party or you typically feel unsafe when solo traveling, just start early (by 18:00-19:00 you can already find many fun stuff!) or just be ready to grab a cab back home. Public transportation at night might not be fun, anyway, even at relatively early hours in the evening.
We found the price very fair, neighborhood is safe, and Xsjong enjoys giving you a warm and extensive welcome. Apartment is clean and spacious, and you share it with another person, so this is perfect for you if you know how to respect coexistence rules :)
