I would say... a wonderful trip could be more fantastic if you choose to stay in Aki’s house, the place which is simple but warm. It takes about 10 minutes walk from 都立大學 station(suggest walk along 呑川柿の木坂支流緑道, it takes less time). Aki is such a friendly host... always responds quickly, provides recommendations for restaurants/traffic, and is willing to help you actively with passion. If you are worried about the sound insulation of the traditional Japanese room... just make sure you can keep the voice down all the time because I believe that every guests here will do it the same(at least during my 4-night stay, everyone got alone well with one another:D ) The shared toilet and bathroom are always kept clean and tidy as well. In a word, I highly recommend choosing staying in Aki’s place for your Tokyo trip!
