Incredible bad experience.
The apartment i booked in Tokyo was in a horrible state to the point i immediately left.
I complained about it at airbnb and i stuck to their rules (Contacted and left within 24 hours of arriving and contacted the host) but no result.
The excuse was that the host had a lot of good replies, while the host is able to accept his own reviews.
Multiple phone calls later no result, multiple promises later no result and 1200 euros gone.
Just never use airbnb you're better off using a hotel.
