After I got my booking confirmation we took a taxi to this homestay (which was hard to find for the driver since it was in a narrow alley). The owner wasn't there because of idul fitri holidays and for some time it was unclear who would help us (lots of people were walking in and out) After some time a friendly lady told us the room (which was booked and payed for) was not available. After contacting the owner the decision was to transport us to a different hotel. She first went there to check if they had a room available and she then took us and our heavy backpacks there on the back of her motor bike. The room had the same price as the room in the homestay we originally booked. Good solution, but it would of course be better if they kept their booking system up to date when offering rooms on agoda.
