I 10000% recomment Wakana's place. I stayed 6 days and it was so amazing: If you are cat lover, you'll meet a handsome and gentle cat who is always welcoming. The room is just perfect and everything is so well prepared (Actually I really surprised the host's kindness and consideration. She prepared treats-cookies and chocolate, lots of informative travel books, ramen, bottles of water, tea, coffee, etc.)
Wakana, she is so amazing. Even though she's busy about her work, always supported, gave me lots of information that I asked, and when I'm talking with her, I feel warm. That much, she's so kind.
First day, she picked me up at the near of subway station, and you'll have lots of info about the good restaurant/cafe/directions to good travel spot.
The location is really nice. Shibuya is so closed by the subway, and the atmosphere if the area is really quite and peaceful.
Already miss Wakana's family and the house.
