Great location: 5 minutes walk from Akasaka tube station (exit 7 is the closest), with a laundromat basically next door, restaurants nearby and a couple of 'family market' and '7 11' on the way to/from the metro.
Breakfast is basic but nice with bread, butter, jam, honey, eggs, bananas, free water and one free drink of choice as coffee tea or orange juice.
Bunk beds very comfy and spacious with room enough for your basic stuff and a small locker inside the cubicle.
Bathroom is very clean and spacious with complementary shampoo, conditioner, body wash and hair dryer.
Bunk beds 10 and 9 of the female dorm on the ground floor are very close to the common space so if other guests are rude, inconsiderate or drunk, as the beds are next to the confining wall, the noise might be annoying if you have a light sleep, so bring ear plugs.
