This place is highly recommended!!
Chanced upon this house when we were looking for somewhere near to the metro station and Shinjuku area. The house is nearest to the Nakano-shimbashi metro station which still requires a good 10 mins walk. (600m) There're direct buses to shinjuku station too, but since we bought the 72 hour metro pass, we skipped on the buses.
The house is very cozy and just nice for 3 people. There's enough space for 3 beds, 3 opened luggages, a mini sized sofa and with all that there is still a small path for us to walk through. Many amenities were provided which includes towels, shampoo, shower, conditioner, microwave, spoons, cups, plates, forks, knife and even chopping board. (The knife may look like a butter knife, but it can cut an apple)
The beds are also very comfy! One down side is that it'll be good if there is a TV in the room for entertainment.
The neighbourhood is very quiet and peaceful. It's quiet at night, and lovely in the morning. There's a convenient store just right by the corner. (but do note that it closes at 11pm) There's also a supermarket and drug store about 5 mins walk away. (it helps a lot for our last min shopping for snacks before our flight home!) - Oh, and the late check out time gives us more time to pack our luggage after getting last min snacks. (Good advantage as many places in japan have early check out time, ie 10am)
Cassandra and Mikoto are very responsive to queries and they are very helpful. Even though we could not check in early, they still helped us to look after our luggages and brought our luggages to the room when we're out. Cassandra even went out of her way to meet us, even though it was already 10.45pm in the night. (It was very sweet of her as not many airbnb host will do that - at least out of my 5 ex airbnb experience, i only met one of the host). She even recommended places of interest to us, and aid us in finding the 24 hour laundry place.
Really do recommend this place to anybody who's looking at it!
