It’s very close to Rokugōdote station and very convenient if you only use Keikyu-line (which takes you straight to Yokohama and Shinagawa station).
However if you would like to use other lines such as JR and Tokyo Metro, you may feel a bit inconvenient. For instance if you’d like explore Tokyo 23 wards every day, it’ll take roughly 30-50m one way.
Overall i loved this place as you can stay for $20 per day including water, drier, kitchen, shower, amenities, wi-fi.
