My stay at Vivian's was exactly what I needed. I had a brief business trip through the city and needed access to the financial district which is right on Vivian's doorstep. The area is nice and quiet, and the room is nice and comfortable.
I didn't meet Vivian herself, but her husband Kenneth was there to host me. I absolutely loved that he leaves breakfast out for you in the morning, not many hosts do that.
I'm visiting Amsterdam again next month and plan to book here again as I'm very happy with it as my go-to place to stay in Amsterdam.
