The place is perfectly located near restaurants, convenience stores, bus stops and subway stations.
It also had everything you might need during a long-term stay, but the laundry machine was most definitely helpful!
The host responded very quickly as well whenever we had questions.
My only issue was that when we arrived, the place has not been thoroughly cleaned--surfaces and floor were dusty. We had to do additional dusting ourselves when we arrived.
Overall, it was a great place to stay at around the Shinjuku area. I am sure the cleanliness can be improved for future guests.
