We booked 2 nights at Akira's place and had a lovely stay. The flat has everything that you need and you even have the notice in English for Japanese device (especially useful in the toilets :) It is close to public transports and you reach Shibuya within 20 minutes or so. The room was spacious enough for 2 people and has a nice balcony where you can enjoy the sun with a cup of Japanese green tea. We definitely recommend Akira's place.
