Hirotaka's place is great. It's right in the center of Shibuya, about 2 minutes away to a lot of stores and food.
The place is quite small, but this is Japan you're going to, so get used to that. The place has a small balcony though, which is awesome :).
It was super easy to check in and check out. The description that Hirotaka sent a week before were super descriptive and easy to follow. That was perfect.
