Dear Mr. Kumar,
I have run my Homestay for 25 years and nobody has ever had a problem. It is an old style property and we maintain it that way. you had booked the Single room which has a shared bath and it is mentioned clearly.
You came at a very late hour did not even stay and have the right to write a review seems a bit bizarre to me.
We still hope you will give us a chance and stay here before you decide on writing a review. if you don't like climbing stairs we have rooms downstairs with attached bathrooms but they are notas cheap as the room you had booked which is the single budget room with shared bath with the Twin room .
It is unethical to write a review without having stayed in a place and not having paid for it either. I question your motive.
