Naoki's place is a nice apartment that's a short walk away from the Takadanobaba station (5-7 mins). Within walking distance are various convenience stores (Family Mart, 7 Eleven, etc), many places to eat (right across the station is a street [さかえ通り] full of different restaurants, leading towards Tokyo Fuji University), and a shopping complex called The Box (right next to the Takadanobaba station) which also has a bowling alley! There is a binder that also informs of these points of interests!
The apartment itself looks exactly as the photos depicted (in my case, the chair and small table were stashed in the closet under the bunk bed). It may not be obvious, but there is an indoor clothesline close to the balcony window where you can pin and hang your washed clothes, and there was an additional portable heater. Additional hangers, an iron and ironing board, and drawers can also be found in the bottom bunk closet. You may hear your neighbors, but I had no problems during my stay, it was overall pretty quiet. I'd recommend it if you're staying around Tokyo!
