Dongs place is located in a great location, very close to Nishi-Shinjuku metro station. It’s also tucked away from the Main Street so it’s pretty quiet. As with most of urban Japan, there’s convenience stores within a ~2 min walk of the apartment, which is very convenient.
The apartment itself is small and is really optimized for 1-2 people, like most places you’ll find in Tokyo, but has all the basics you need for a stay in Tokyo.
I definitely recommend this place if you want a quiet, metro accessible apartment.
