Good:
Staff is very friendly. Breakfast is good.
Bad:
a) Very noisy. My room was located next to the lift which makes a machine noise everytime it goes up and down. Another annoying machine noise came in somewhere unknown, all the time even at night. The hotel is close to the Copenhagen Central station (~10min walk), and a lot of guests / families came in and out with talking - even at midnight and early morning. In addition, the hotel is faced on a major street, and some motor-bikes generated unnecessarily big sound especially on weekend. Very uncomfortable with all these noises, couldn't sleep well.
b) The room is 1) light-cleaned every 4 nights, 2) full-cleaned once a week. If you stay for several days, you will need to be with a full of trashes and to keep using the same towels and bed sheets until the next cleaning is done. The hotel noted that this cleaning cycle is for green environment, but it sounds like telling that you have to "be patient" for it.
c) WiFi is available, but no security. Make sure that you have your own VPN, otherwise dangerous to connect.
d) There was a temperature control, but not sure if it was working or not. The control is simply a plus-minus dial, no switch, no temperature display.
