This place is simply the best - it’s family friendly, quiet and convenint to groceries and stations (Shinjuku San-Chome and Shinjuku stations). Seiji is also an amazing host - he communicated in English very well which was extremely helpful for those of us non-Japanese speakers. He was quick to reply and also provided step by step instructions how to get to his place and tips on where to eat around. I will definitely consider staying at his place again when I visit Tokyo next time! Thanks Seiji!
