Ranka was an incredibly nice and accommodating host. I enjoyed my stay at her place. The apartment is right near Sangenjaya, which is a great area filled with good restaurants and cafes . From Sangenjaya, you can get to Shibuya, Shinjuku and Roppongi very quickly. Ranka was also responsive. The place is quite small so long stays are best if limited to one person (I was there for a month alone and it was perfect).
