Even though we never met, Seiji was always availableand helped us promptly whenever we needed. The house is small but has everything you need, and furthermore Seiji provides plates, pans, cutlery, some condiments and all sorts of soaps. The house is very central and Shinjuku Sanchome is so well connected! Lots of konbini all around. Will be back if we ever get to Tokyo again and the house is available ;)
