We stayed in #202 for a month. There are several air bnb units in the building. Importantly, the air conditioning was excellent, the beds very comfortable and it was mostly very quiet. The portable wifi was great. The location was very convenient- 10 minute walk to the subway and bus stops which are both easy access to Shibuya centre and Shinjuku. There is a 24 hour grocery store at the station which had everything we needed - veggies, dry goods, cereal and so on. And a couple of convenience stores 5 minutes walk.
We saw Masami when we checked in, and once more when she needed something from the cupboard. She responded to our one message quickly. There are booklets to explain the use of the apartment equipment.
The apartment was fine. Very clean. We bought some bowls as the cupboard has glasses, mugs and side plates. There is a toaster oven, microwave and a 2 burner gas stove. The fridge has a good sized freezer. There are 3 frying pans to cook with. We bought an air freshener for under the sink.
The bathtub is great and the bathroom has a warm air drying cycle for laundry. We didn't use the washing machine. The living room area was comfortable. We turned on the TV to check it out and turned it off again just as fast. The two air conditioners were fantastic. The apartment stayed pretty cool during the day when they were turned off when we were out. There is a place to hang clothes in the entrance way where the cleaning supplies are kept. The cupboards are used for mattresses and bedding for when there are multiple guests. We put clothing up on top of the mattresses and tucked one suitcase on the floor in the closet.
Overall the apartment was an excellent choice for us and we would recommend Masami as a host.
