I lived here for more than 5 months in 2 different rooms.
I would say this is the best for 1~2 people staying together.
It could fit one person with many luggage.
1) Very convenient room, with all required facilities such as washing machine, TV, high-speed internet and two comfortable beds.
2) 5 minutes to Hamatsucho station and Daimon station.
3) 3 minutes to Pony cleaning for laundry.
4) 3 minutes for specialty coffee.
5) Secured and modernized.
6) Varieties of restaurants and shops are available within 7 minutes distance.
7) Hamatsucho is located between Tokyo station and Shinagawa station for the Bullet train, close to Tokyo tower, gold gym, malls, and two public parks.
