The apartment is perfect, rather large for an apartment in Tokyo, very clean, very quiet, true to the pictures, pretty close to the metro and central Tokyo, there is a supermarket just down the apartment open all the time!
I could not talk much with Manami because I don't speak English very well but Manami is really adorable, she offers to pick you up at the metro for you avoid the hassle of Japanese addresses (not easy to understand because it's a numbers system) but the apartment is easy to find, it's still all right!
Manami don't live very far from the apartment, she is available in case of trouble and she can come quickly.
She is a perfect hostess, I recommend her!
I hope to return very soon.
