Yuka and the Zens team are always there to answers any questions we may have about anything related to Tokyo. The place is clean and there are several small restaurants & bars within walking distance, so it's very convenient. The place is a bit far from the main JR line (the big Shinjuku station), but you can always take a local subway to the Hatagaya station from the Shinjuku station. Overall, it was a very good experience.
