well i booked there for 2nights
i'm a foreigner so i didn't have a japanese sim card i only could contact them while i was using wifi however when i arrived there i called owner many times but they didn't answer me and i was waiting infront of the building around 3hours if i could find someone but unfortunately no
and consequently i didn't stay there totally and i requested them to pay me back at least 70%of price but they declined . money didn't come back
maybe it doesn't often happen but i'm just very disappointed
