This was my first experience with Airbnb, had a very pleasant experience which led me to try this again.
The room was immaculately clean and Frau Rukie (André's wife) was very helpful.
Beds were comfortable and clean, fresh pillows and towels were provided.
Location in a quiet neighborhood not too far from the center and very close to the museum quarters.
The Feiners are very flexible, just message them and ask if you need a single bed, a double bed, they even have a spare room with a kitchinette if you are a family.
Will definitely stay there if I ever go back to Amsterdam,
