There was no GPS around apartment so it was super difficult to find in dark. The building was on very small street and Sign was very small and not clear at all. Also I called host during check-in hour but they never took phone or texted me back at all. I had to ask exact location on the street and it took more than 30min to find out.
Also hot water was very limited bc they used small hot water tank. When water run out, you have to press the button on the tank but there was no English instruction. I had to figure out how to do it by myself bc again host did not response to me at all more than 7 hours. I have stayed two other Airbnb in Tokyo but this place was worst experience I have had.
