Hirotake's place is in an excellent location, a few minutes from Shimbashi station. We went all over Tokyo and didn't have to change trains even once. The apartment is stylishly decorated and clean, the ceiling is high, the beds are comfortable and large enough to hold me (6'4").
Also, Hiro was easy to reach and quick to respond. We really had a great time!
Just remember that the front door has two locks! It took me a few minutes the first time to find out how to enter :$
