Daisuke's place is an incredible opportunity for a solo traveler or intimate couple looking for a taste of the real northern Shibuya life. Be aware that the heart of Shibuya like Shibuya crossing and whatnot are about a 20 minute walk away, but that for me was better, since there are two train stations conviently right nearby (Yoyogi-koen and Yoyogi-hachiman) that can take you to Shinjuku or Shibuya station quickly. The bar underneath was one of the best parts of the experience. Met some very awesome locals who will be lifelong friends. The Tatami room touch was just what I was looking for, but the thinness of the futon and sleeping on the floor might not be for everyone.
I don't think you can get much better in Tokyo for the price if it's what you're looking for!
頑張って！
