Aki's place is spot on for visiting Tokyo! 4 people per floor is perfect space wise 8 people per floor might be a squeeze but still copable.
There's about 7 convenience stores right near apartment, aswell as the train station on the Odeo Line.
there is a Coco Curry, McDonald's, Sukiya and more little resturants less than 5 mins away.
the rooftop doesnt have a crazy view but is decent enough to chill out on and have either a few beers or a cuppa.
Its 20min to Akihabara(Train)
15min to Shibuya (Train)
20min to Shinjuku (Walk) even sooner for train.
I recommend Aki's Airbnb because she is very quick at responses, you can pretty much get to any main place within 20min, it has decent beds (not the best but decent) and the convenience of the subway and stores nearby!
