Sayoko's house was very nice and very clean. But the house location is a bit far from JR Osaki Station (10-15 min. walking distance).
JR Osaki Station is really good location , just 15 min. to Shibuya , 20 min. to Shinjuku or 30-40 min. to Yokohama. And you can take a bus to Narita Airport at Osaki Bus Terminal by Willer Express. Also you can take a subway line at Togoshi Station.
The house close to Togoshi Ginza , there're local shop more than 200 shops , there're everything you need.
Highly recommend.
