Vivian’s place overall was great. It was a reasonable walk to train stations, and a good location to be able to easily get to other neighborhoods in Tokyo. It was super clean and very comfortable and we’d definitely stay there again.
The only cons (and they are very small) are
1) the bathroom lighting was pretty dim and placed in a way where it was very hard to see yourself to apply skincare or do your routine
2) there is an exit sign inside the apartment that shines very brightly once all lights are off and curtains are closed. If you are someone who is sensitive to light as you sleep definitely bring a sleeping mask.
3) the closet was slightly small but not a huge deal - just something to consider if you have a longer stay.
Overall we enjoyed our stay!
