Sayoko's place was clean and cozy. She was very helpful during check in and check out. She went out of her way to ensure we found her house when we arrived. For that we are very grateful. During checkout she also went out of her way to drive us to the bus terminal our with our luggage.
The wifi was great, would recommend to bring an external battery in case you are out for the whole day.
Easy access to the train station and shibuya was only a couple of stops away. Same with odaiba.
It was cold in the apartment but there are several heaters provided. The room heats up quick and the heater in the bathroom is a plus.
