My fiancee and I stayed here with another couple and it was a perfect base for our week in Tokyo. The neighborhood is residential, but there are tons of little restaurants and shops tucked away in the alleyways and streets surrounding it. We found it really fun to explore, and took a different route home from the subway stations each time.
The home itself is very quaint and delicate, and you do have to be careful and respectful of the space. However, we really loved the character of the home and felt it was a perfect complement to our stay. It was impeccably clean, has a great shower and a bidet (we loved the toilet seat warmer), and a washer/dryer. The pictures of the home are very accurate.
Two major subway stations are located within a 10-15 minute walk of the home, and we were able to get around Tokyo with the help of Google Maps. Although the home has WiFi, I would highly recommend any visitors to rent a portable WiFi unit, as it really helps to be able to search the web or use your map while roaming around Tokyo.
Transportation is confusing if you don't speak Japanese, but Google Maps will give you accurate train times/directions. We used the Pasmo cards (electronic cards that you can load value onto, to use for trains/buses/subway), and left 4 of them there for future tourists to utilize.
The Tokyo SkyTree center is very close to the home (20 minute walk) and it has great food and lots of shopping. The Asakusa district is only a short bus ride away, and has a variety of shopping and restaurants. Just west of the Asakusa district, you will find Kappabashi Street, which is where all the restaurant supplies are sold, including the fun fake food you see in all restaurant windows, and beautiful dishware, ceramics, and knives. Absolutely worth a visit. We also really enjoyed the Meiji Shrine and the Harujuku District, which you can easily get to via the subway.
We really enjoyed our stay and would not hesitate to stay in Akiko's home again. Taro, Akiko's assistant, speaks perfect English and was very helpful and accommodating - meeting us at 11pm on a weekday, when we arrived. A very special Arigato Gozaimasu, to Akiko and Taro!
