The hotel overall is okay, price is good, just that one of the front desk guy is quite impolite.
When I walked back into the hotel and tried to get some water from the water dispenser at the main lobby, a front desk guy asked quite abruptly "Do you stay in the hotel?" I told him my room number. I don't remember I was being interrogated like this ever when I walked in a hotel anywhere in the world.
Also they don't have water kettle to let you boil water in your room. That same reception desk guy asked me to go to the coffee room on each floor to get hot water. But then I wasn't sure which button to press for hot water, the guy lectured me how to spell hot water in German.
