The room that I rented is small size no 25 ... The tone can not go up and down even though it has pressed the key up and down. More broken and incompatible between text and tone. Already called IT but could not be handled and did not want to check again but left without any clarity. I have to spend 2 hours with a disappointing experience just because I paid using a traveloka experience voucher, it seems to be underestimated. Next concern for customers please be the same, don't be discriminated.
