I booked Ken's studio for one week. I was looking for renting apartment while I was living on his studio. I got an apartment on Tuesday and let him know that I will move on Wednesday morning.
I wanted to cancle for last two days like Wednesday and Thursday. I informed him well-ahead around 6:45pm on Tuesday. Please note, for Wednesday if someone want's to rent it then the day will start counting from Wednesday 3:00pm.
I have requested for cancellation for last two days but, he didn't accept my request. Generally, 24 hrs notice is applicable for full-refund. If we consider that then at-least I should get refund for the last day but, he didn't agree to accept my cancelation request.
In summary, although I left his property on Wednesday but, I paid him until Friday as I booked it before and paid before until Friday. It seems once you paid, you are stuck and there is no way back.
