Tomoyuki is a great and responsive host who cares about his guests. Though I did not get to spend much time with him myself due to my own schedule, he made it clear on multiple occasions that he's willing to provide help and tips.
One thing to note about the neighborhood is that it retains some pre-1980s urban Japan atmosphere. There are many local shops and restaurants that have such a vibe, so if you are into slightly-old-but-not-so-old feels in Japan, Tomoyuki's neighborhood is an excellent choice. Tomoyuki also knows some good local restaurants. :)
