The apartment is about 5min walk distance from NishiNippori station which is one station of Yamanote line. Yamanote line is very useful for your first trip to Tokyo.
It's very clean, warm and sweet apartment. Everything is very good when we live in there. Of course it'll be perfect if the price is lower:)
One advice, if there are 2 keys for lodgers it will be more helpful.
Thank you Yoshi and your partner.
