Yuichi's place is located in Nishi-Ogikubo, a small, quiet town. The apartment itself is only 3 minutes walk from the train station and 2 minutes walk from the closest 7-11. There are a few nice restaurants in Nishi-Ogikubo, but most of the time you'll want to explore other parts of town.
By train it's only one stop (or a 20 minute walk) to Kichijoji, a great town with lots of cool stores and restaurants. It's about 20 minutes by train to Shinjuku, one of Tokyo's biggest and brightest neighborhoods.
The space itself is large, quiet, and a great value. It could comfortably sleep 4 people. It's pretty basic, but all of the necessities are provided.
