If you are looking to spend some time alone in Tokyo, I recommend this appartement. It is small, (japanese style) but has everything you need. it is door to door 15/20 minutes from Shibuya or Shinjuku Station, 5 minutes walk to Shimokitazawa a very nice, cosy and trendy neighbourhood.
Kuniaki-san was easy to communicate with and has an agent in the building that is around everyday in case there is something you need or any problems...I didn't call him once. everything was perfect.
Also works for a couple that travels light!
It was very relaxing to come back to a quiet house after the hecticness of Tokyo city.
Would definitely not choose any other area to stay if I come back!
Thanks again! ありがとうございます ! ^^
