This place is nice, if a little expensive for a small room with a shared bathroom. The is not breakfast, contrary to the listing title being "B&B".
The hosts are very nice.
As other reviewers have mentioned, there are rules pasted in the room - one rule is that you cannot enter the kitchen. Confusingly, the airbnb description says you can use the fridge. I didn't have anything to put in the fridge myself, but I imagine it would be difficult to use the fridge and not enter the kitchen.
The shame about the rules plastered everywhere is that it makes you feel like a hassle to the hosts, and not especially welcome. I would not say that this ruined the experience, but it does detract from the ambience.
Neighbourhood is nice, and very chic - there is not much to do at night around the area (although many cafes in the day-time). While it is nice to not be in the heart of Amsterdam, which is a mess, some people might like there to be a few late-night things to do in the area. Others might rather a quiet location - this location is perfect for the latter.

I would have been very happy if the place had a private bathroom, or at least did not have rules - I know it sounds weird to complain about it, I thought so too when I read it, but it just makes you feel slightly unwelcome.
