The apartment is close to ideal if you want to stay near Shinjuku, but still experience living like a local. Nakano is an interesting area itself and has some nearby attractions (e.g. Koenji and Kichijoji) that is worth visiting, especially if you've visited Tokyo before and are looking for less touristy places. The apartment is within easy walking distance to stations on both the Tokyo Metro and JR subway lines, which made going anywhere convenient. Just outside one of the stations (Higashi-Nakano) is a major grocery store called Summit where I was able to buy drinks/snacks/fruits for cheaper than anywhere else. There are plenty of convenience stores, restaurants, and drug stores between the apartment and subway stations; I was curious but hesitant to try the nearby restaurants though as it didn't seem the staff speaks English. Note that if you have heavy luggage, you will have to carry it up to the 4th floor. Overall, the apartment was super clean, convenient, and had all the amenities I'd expect from a hotel.
