The good:
Great location, pretty clean place, everything is functional. Hosts respond quickly which is appreciated. Beds are comfortable.
The bad:
The narrowness of the access (plus the 16 outer narrow stairs) makes it incredibly difficult to make it to/from with suitcases. The place is small - just enough room to turn around downstairs and that's about it. The genkan is extremely narrow. None of this is necessarily an insurmountable problem, it just would be better if it was made clear up front so proper expectations were set. The cooking appliances are perched up above the refrigerator with the plug even higher, and there are not enough plugs so you have to swap - and people of average height or lower will have difficulty.
The ugly:
We extended for a day but the key system was messed up and we got locked out in the middle of the typhoon and got soaking wet.
