Very clean and wonderful amenities in a great location.
We took full advantage of the kitchen and espresso machine. The beds were very comfortable and the hosts were great.
You can hear some street noise on busy nights and footfalls and other impact sounds from upstairs, but this did not really bother us during our stay. You may wish to bring ear plugs if you stay during the weekend and are a light sleeper, but I would advise this for anyone staying in downtown Amsterdam.
Also, the bathroom was very nice but does not offer the same kind of privacy we were used to. My partner and I were fine with this but did not feel 100% comfortable using the restroom when my parents dropped by to visit.
