Marielle is one of the best hosts on Airbnb. She was super prompt with all the messages. The place is lovely and spacious. There are no surprises- it fits all the detailed descriptions of the place on the Airbnb.
I am sure you have read from other reviews about steep stairs- yes they are super steep and it would be very difficult to carry anything up other than a simple carry on size suit case. For me, I don't mind it and it's not something that surprised me- I expected it because I read it in the reviews and Marielle reminded me several times. Location is golden- 15 mins walk to Concertgebouw, Van Gogh Museum. Getting to this place from the airport was super simple- just take the bus which takes about 30 mins and drops you off 5 mins away from the place.
I can't say enough good things about this place and this host, but I do recommend someone who might have trouble with stairs to reconsider.
