We stayed at Minami's Airbnb for approx. 4 nights and while some may consider it good value we personally found quite a few drawbacks even given the low price. This is not my first Airbnb or Trip to Japan on a budget.
I'll mention the problems so others are aware. 6 Rooms sharing 1.5 bathrooms and 1 refrigerator. Our 2 person room had barely enough room to place your luggage and stand. We had two carry-ons and 1 standard sized checked luggage.
I realise other reviews had mentioned the Thin Walls but I don't think one of the walls we shared even counts as a wall because it was literally a closet door which was fixed in place. Not only can you see the light peeking through but I am not exaggerating when I say you can hear them eating.
It doesn't help that even with Ear Plugs particularly loud roommates can still be heard especially in the mornings if people shower, use the washroom or don't open/close the front door gently.
