Vivian’s place is in an awesome area of town, one of our favorite in Tokyo. The apartment is very clean and as advertised. It was nicely sized for our family of 3.
Yes, the stairs up to the 4th floor can be a bit hard to navigate, especially with luggage, but their team was there to help at check in, which was especially appreciated as my wife and son were arriving before I was.
One thing to note: the kitchen and fridge are very small. If you’re looking to cook, this may not be the place for you. That being said, it is in a brilliant area for restaurants so we didn’t miss it. The yakitori spot 3 or 4 doors up the street is not to be missed.
