Tatsuki was very accommodating when we had checked in early the day we were supposed to arrive. His place was clean, but just a bit cramped if you have luggage. The location was extremely convenient. It's just a few minutes walk to Shin-Okubo if you need to take the Yamanote line to get to areas to sightsee. In the other direction is Okubo station for the Chuo-Sobu line. It's also close to a Don Quijote, which is a great place to buy souvenirs at discounted prices.
