My friend and I spent the last night of Japan trip in Mr Ohkubo 's flat. It is a stylish and cozy flat with the basic electric appliances and life necessities that you may need. The flat is near to Shinjuku station and your can easily find delicious restaurants nearby.
Mr Ohkubo is very helpful and welcome although we didn't meet. He made a detailed pdf instructions on how to get to the place. He even left some special souvenirs in the flat! Thank you, Mr Onkubo.
