Location of the place was amazing! Only a 10min walk (at most) to a huge train station with many lines to get you all over Tokyo. We loved the neighborhood, has lots of great bakeries and restaurants around and a really good coffee spot 5 mins away (MOJO Coffee). There are also many areas in walking distance with bustling streets (lots of food and entertainment) and other train stations. Just around the corner is a massive supermarket which we went to almost everyday to get fruits and drinks.
The apartment was clean and spacious enough for 2 people considering Tokyo standards. The bed was comfy and there is everything you need in the apartment. The only downsides for us was that there was nowhere to hang your towels, and no full-length mirror - only a tiny one big enough to see your face, which was a bit of an inconvenience considering we stayed there for 10 days. The walls are quite thin, but we are heavy sleepers so it was not an issue.
Overall it was a great stay and Kimie is a great host who is quick to respond!
