Our stay at Lora's apartment was great. The owner (Lora) has warned you in her comments and others have commented, but the steps are especially steep! We have rented apartments in Amsterdam and knew what to expect (sort of). Also, we travel with only a carry-on; I'm not sure you could safely get a large suitcase up the steps.
Some pros/cons that I hope will help.
PROS: Excellent location; lots of windows with daylight coming in; very clean; nice linens; good-sized space with privacy for 4 adults; great communication with Lora; nicely decorated; plenty of dishes/glasses/utensils in kitchen; toilet is separate from shower area; one bedroom very large and other is a good size with efficient storage
CONS: Don't really get a view from inside living room (there are lots of windows but they are slanted up so it doesn't provide a view); no key at check-in (we arrived at 3:30 and key was not in box; had to call Lora and fortunately she was home and came down immediately - but it cost us an international charge to call her. I think she had a new cleaner who was just finishing cleaning and I assume this is not the norm, but it did give us a little fright; plus side to this was that Lora helped us with a bag since she had to come down to meet us!).
Overall: wonderful stay and would stay again (even
