Beware of the AC control: default setting will make the AC system HEAT the room to an unknown degree (!) when outside temp goes below 18 degrees in summer.
Thus a horrible first night, since the hotel is not staffed at all between 22 (10pm) and 14 (2pm) the way to turn this system off completely was given the following evening with the hope that it would be more comfortable. A fan provided was tried but intolerable with the draft and noise. So the second night was spent knowing the time exactly from nearby church bells through the open french balcony door.
Nice breakfast restaurant and very kind receptionist with a creative manager on the phone tried to make up for the RiKu hotels belated negotiations with the AC provider to change the settings.
