Sayoko's apartment was really great! It was really spacious compared to the other apartments I stayed in while in Japan. The location was also pretty convenient. It was close to Osaki station, which was perfect because Osaki is only a few stops away from Shibuya and other large stations such as Tokyo station.
Sayoko was a really wonderful host. She was always available and responded quickly to any messages. The last day she even took us in the car to the train station which was great since we had pretty heavy luggage.
The amenities of the apartment were excellent. She had everything you could want. A pocket wifi, a clothes iron, a washing machine, great little kitchen to cook, and others.
Overall it was probably the best place we stayed in during our trip to Japan. I highly recommend it!
