Had a great time staying here! 5-10mins walk from the nishi-nippori station. Easy to get to, nice neighbourhood with convenience stores/atms and restaurants. Also near JR Yamanote which conveniently goes to the major stations/locations in tokyo. A bus that goes straight to asasuka is located on the main road in front of the house - again, very convenient. The room is big, with a comfortable bed, and has all you need. There is also a nice onsen 10 min from nishi-nippori station, and tourist spots such as the yamanda ginza and yamanda cemetery.
Kotaru and kei are very accomodating and nice - experienced around foreigners and speak good english. Miya is also very friendly! Kei has a cooking class (bento or gyoza) which was a cool experience - so book yourself in if you’re interested - it was delicious, filling and fun, cooking with other travellers!
Highly recommended, particularly those who want to experience what it is like living with a japanese family or in a ordinary/modern japanese house.
