Shinichi's place is as described. Extremely clean, convenient and accessible to shops, train stations, cafes, major outlets and eateries. It is a stone's throw away from the two major stations on the Yamanote line [Green] being Osaki and Gotanda. As such, it is easy to get around to all major tourist spots in Tokyo and the larger metropolitan area. Major access points to Osaka, Kyoto etc via Shinkansen is along this green line - Shinagawa.
There are numerous eateries, izakayas and shops in Gotanda. This is indeed a major residential area and as such you will feel like a local residing and travelling to/fro from your place.
The showers are incredible in this place and i felt safe anc comfortable. Wifi was fast and easy to connect to...a pleasurable trip all around.
