Everything was great! Ronny gave me really accurate instructions to get to the apartment. So it was easy to find.
It is only few minutes away from Shinjuku station.
Around the apartment you can find many places to eat, 24/7 convenience stores and a Salvation Army (Really cool place to buy traditional japanese souvenirs).
The apartment itself is full equipment. You even have cable tv and hight speed Internet.
Nothing to complain about!
Thanks Ronny!
