Kofumi's place is indeed an amazing place for our 1st ever trip to Japan. It is a real value for money. I have checked with my Japanese friends, that with this same amount, you can only get a hotel with only one-third of the size of the Kofumi's room. Moreover, Kofumi gave us extra services by providing some snacks, and most importantly: Portable wifi router (which may cost me SGD 5 er day if I rent from outside).
The room comes with amazing amenities: toilet heater, good shower heater, room heater, complete kitchen utensils. The bed is also very comfortable. As a person who cant sleep easily in a new place, I was surprised that I could sleep well on my 1st night at kofumi's place. The host is also very reachable as they are just staying 1 level above us.
