We loved the aesthetics of Naoko's place! It was the biggest apartment we've stayed in Tokyo, which was great. The bed was also the most comfortable bed...great after a long day of exploring Tokyo.
The apartment is about a 10 min walk to the metro station, but once you're on the train it's quick & easy to get around.
Because the highway is right in front of the apartment it is noisy. But Naoko was kind enough to provide ear plugs, which was helpful. After a day or two, you kind of just get used to it.
Naoko was also very responsive.
