Junko's Koenji apartment was quite comfortable. I feel it was on the large size for a Japanese apartment; I've certainly stayed in much smaller ones! I've stayed at five or six AirBNBs in Japan, and Junko is the only host who has met me at the apartment for check-in. I found that to be really helpful, as she answered any questions I had at the time. She really cares about her renters: when there was a very minor earthquake while I was there, Junko messaged me to check and make sure I was okay and felt safe. She was so kind! Having the clothes washer in the apartment made a big difference! I dried my first load on the drying rack Junko showed me, but subsequent loads I took down to the self-serve laundrymat to use their dryer; it's really close. There's a clothes rack for shirts and stuff, and drawers for socks and underwear. Really handy. There's a Family Mart mere steps away from the apartment, so it was easy to get snacks and stuff anytime of the day or night. The only potential drawback is that the toilet is a bit cramped, so if you're a big person, you may need to squeeze yourself in there. Overall, I loved my stay at Junko's apartment, and I plan to stay here again the next time I visit Koenji (which will hopefully be soon!)
