First of all, we would like to hank you very much for staying at the listing!
As you said the stairs could be difficult to go up and down for some people. We have a note that stairs are steep on airbnb description as well as photos on our listing page. However we are sadden to hear how you felt about our place. It might be not as comfortable as western houses, but we would still like to recommend our place for those who would like to experience the real traditional Japanese architecture.
Also, we have pictures on our listing page to show guests what the whole house looks like at our airbnb. We were hoping these information help our guests to understand how this house is like, and we hope this is enough for our valuable future guests to know the house condition before making a reservation.
We do regret to hear how you felt about our place, and will definitely take your valuable opinions into account for our future guests!
Thank you for leaving honest opinion, and we do hope you have enjoyed your trip otherwise.
