I don't recall seeing any kettle and cups, but there might have been some mugs. If you take a room with kitchenette you'll have a microwave, an electric stove and a fridge - so you have some means to heat or chill water/drinks. I believe you have to pay extra for cutlery as it is not supplied by default.
I am not 100% sure as to whether there is a kettle and cups but as the other answer says there are means to heat something up. We didn't have a bottle opener so asked at the desk and they gave us a wine bottle opener to take up so maybe if you ask at the desk for mugs etc. they will help.
