While the Hilton staff provide unparalleled hospitality, my rooms were underwhelming. In the first room, the AC didn't work, with temperatures reaching 25.5 C / 78 F at night. Once changed, not only did the AC not work in the second room, but a large skylight allowed nighttime ambient light in + a fully bright room at 530 AM. I was offered to move rooms again, which I declined, given packing and unpacking two nights in a row for a three night stay seemed exhausting.
