Wakana is an absolutely wonderful host! Loved my time there. Listen to her advice on local restaurants, seriously. Super close to Ikenoue Station, which is only two stops away from Shibuya. Very calm neighborhood, with a 7Eleven and a Family Mart close by. Very comfy room, and tons of guide books in the closet! Even if you haven't planned anything at all to do in Tokyo, these books got you covered. If you have some time, definitely have a conversation with Wakana! She is an incredible person.
PS: The cats are adorable, really really. They will want to get into the room, so remember to lock the door if you're not comfortable with them just hanging around there (they can open the door if it's not locked and it's super cute).
