The location is good and there are plenty of accesses to public transportation within 5 minutes walk distance. It takes about 10 minutes to walk to the Shinjuku station and it takes about 5 minutes to walk to Kabukicho Ichibangai area.
The apartment itself was really clean and neat. The owner of the house offered us many appliances which came handy (like portable wifi...).
Overall, I would say it's a good place to live in Tokyo.
