My friends and I enjoyed stay in Emi and Tuhin house , it very nice , clean and comfortable for us (my group have 7 people). The hourse is near the jr station (Koenji) , just 5 min by walking , and it take around 10 min to go to Shinjuku which is very fast. The location is great , there are many restaurants and convenience stores nearby. In addition , there is free pocket wifi which make everything more convenience.
Emi and Tuhin are so friendly and kind :)
