The apartment is in a very quiet neighbourhood in Amsterdam, but still not far from the city center, connections are frequent and fast. A highlight is the NDSM, which you can reach by foot and then take a ferry to the train station.
Nima seemed like a very nice person, even though we only got to talk for a short while. His instructions for getting to his place and checking in were also very clear.
The apartment itself and the room is very spacious and overall pretty clean, although the table by the bed and the floor were a bit dusty.
Would recommend!
