Shin is a good host, the appartement is for sure totally in the atmosphère of Tokyo. Narrow and high. Little dangerous if you come back drunk, it is préférable to not try to climb at third and fourth floor. the fact to have access to the rooftop is also good. location is good. Close to Shinjuku and have a lot of small bar and restaurant very good around, I would like give adress but too much are good, owner play shamisen and sing, one Okinawa restaurant is also very good Shin knows now the place you can ask.
For quality price you cannot find better, especially in this location.
