This is a great apartment in a very convenient location. Shibuya offers easy access to a lot of other neighborhoods both by train and walking. The area around the apartment is a red light district that offers a great variety of things to do.
The apartment itself is very basic, as you should expect from most apartment offerings in central Tokyo. The 10th floor balcony is a plus, for sure.
All in all, great booking. Water was hot, bed was comfortable, and the host was top notch.
