This place is an easy walk to a lot of great attractions and restaurants. The elevator was super helpful to have because we had a piece of heavy luggage. Simon, Menno's son, checked us in and he was very friendly and very helpful throughout our stay; his communication is very prompt. The bed, as others have mentioned, is super comfortable and spacious. The kitchen has everything you need to reheat leftovers or make a quick breakfast. It is a small studio, so you won't have a lot of room to move around if you have multiple pieces of luggage, but it's likely you won't be at home much anyway since there is so much to see in Amsterdam.
The studio is on the same floor as another Airbnb unit, which at the other end of the hallway. Something to note is that the though the bathroom is private, it is in that shared hallway (it's not in the studio itself), so you will have to exit the studio to access it. The host has thoughtfully provided a couple of bathrobes for this purpose.
