If there's only one reason you need to take Yoshi & Rio's place, I'll give you three: location, location and location. It's right in the heart of Harajuku and you will never run out of options of places to eat or shop or simply walk through. It is close to many modes of public transport too. My friends and I spent only two nights here, but we would have loved to spend more.
The living room is cosy, and the bedrooms are comfortable, albeit functional. I would certainly recommend the place, especially if you want to be in the heart of the action.
