Rintaro's place is in the amazing Sangenjaya area. It is buzzing with small bars, drinking alleys, restaurants and cafes (you'll never go hungry!). The apartment itself is conveniently located a 7-10 minute walk from the Sangenjaya subway station and is a great base for seeing Tokyo, with Shibuya just two stops away. You can also easily walk to Shimokitazawa, a cool hipster neighbourhood, from Rintaro's place.
We fit four adults into the two bedroom apartment. Bit of a squeeze, but for a week's stay it worked. The apartment complex itself is one of the nicer ones available for this price and definitely good value for money. If you're looking for a comfortable place to stay while you're in Tokyo, Rintaro's is a great bet.
The only watch-out is the subway line to Sangenjaya is one of the busiest in Tokyo, so be aware you may have to get used to a sardine-can style commute to and from the apartment.
