My cousin and I stayed at Ken and Kazumi's place for 4 nights. It was supposed to be 5 but the layover flight was late causing us to miss our flight to Japan. The apartment is very clean and comes with all the amenities mentioned. I was very fond of the Pocket WiFi as it's my job that pays for my cell and data was limited on the trip. Anytime I had a question Kazumi was quick to respond and help me out. This was my first trip to Japan and I was worried because of the complicated rail system. The instructions provided to reach the apartment were so clear and precise that even if you tried it'd be impossible to get lost. I was so overwhelmed by Japan and didn't know how to make use of my limited time here as my itinerary was thrown out of balance. Kazumi was there to help though as her recommendations on spots to go to helped make my trip more enjoyable. If you're looking for a helping hand and someone there to help make your trip the best it can be then I highly recommend Ken and Kazumi's place.
P.S. if you're a foodie there's lots of spots you can hit in close proximity to the apartment.
