This place is near the main road in Shinagawa. I slept 1 hour a day because noise of driving cars interrupring me. The bed has springs which you can feel with just puting your hand on it. You wrote that it is good place to work but from my point of view it isn't because is hard to work after 1 hour of sleep with pain caused by springs in bed. If someone like to smell used towels they are waiting for you in wardrobe... I want to forget about this experience. I want to recommend the owner to sleep there for few nights before share this apartment for anyone. Propably I will never choose AirBNB after this reservation.
