Cute space in a wonderful location! Our group of 5 could not get enough of the giant, sunny living room windows and pretty canal view below. The flat is on a quiet street just around the corner from a little park with two nice outdoor cafes where we often hung out for meals and drinks. Convenient walking distance from amenities (two grocery stores and a good coffee shop within a few blocks) and the Jordaan neighborhood.
We did not meet our hosts in person but they were very helpful and prompt to respond over email. We appreciated the bottle of wine they left us as a welcome gift!
As others have noted, it's important to be aware of the steep stairs. Carrying heavy luggage up will be a struggle. But my 65 year old mother (who has had knee troubles in the past) was able to make it up and down just fine so I think it's simply a matter of getting used to it and not over-packing. Also worth noting that the weather was unseasonably warm while we were there (80 degrees), so the bedrooms did get a bit toasty at night on those hotter days.
