We had a good stay at Yi's house. The unit was sparkling clean and it was exactly how it looks like in the pictures. Microwave, washing machine, pocket wifi, and others amenities were all provided. It's big enough to fit in 4 guests. But you have 4 big suitcases as well you may have to take turn to open your suitcase as the space is limited. Yi was friendly and provided very quick response and tried his best to answer our inquiries during our stay. Self check in was easy and we had no problem on that. A little short walk from Nishi-Shinjuku Gochome (12 mins) and many convenient store and shop nearby. Overall a great stayed for us during our trip in Tokyo. Thanks for hosting.
