Large apartment for Tokyo. New. modern comfortable furniture. Great detailed english instructions on how to get to the apartment and how to use the appliances
Location is close to Okubo line as described and a short walk to Shin Okubo line which is on the main JR rail line, Yamanote line. You can also walk to Shinjuku station/area; it is about a mile. Shinjuku is know for its shopping and there are many restaurants including the food malls in the basement of the large department stores.
There is a grocery store on the first floor of the building in which the apartment is located which is very convenient for getting snacks. On the way to the Okubu/Shin Okubu line there is a bigger version of the same grocery store which has a wider variety of food. The street the Okubo and Shin Okubu station are on has many types of stores including 7-11 (get cash if you are from the US), restaurants, bakeries, and a variety of other shops.
Overall a great location and not nearly as touristy as some other areas of Tokyo.
