It was the first time myself and a group of friends were going to Japan so we wanted something close by to pretty much everything.
This place that Kei is offering is pretty much what you want if you're going to be staying in Tokyo. Its about a 5-10 min walk to 2 different train stations (which JR Pass works) and you're minutes away from downtown Shibuya, Shinjuku, and Harajuku.
Amenities were enough for 8 people (one person slept in the living room area). while the rest were situated in the other 3 rooms.
Close to many restaurants and Family Mart/7-11s.
From check in to check out, everything was smooth as silk. Not to mention great communication. I recommend booking this place if you get the chance. You won't regret it.
