Fantastic stay --- our stay was really the best of both worlds with the space of a large apartment and the easy communication / issue resolution of a hotel. The City Square team provided extra fans because it was so hot and extra pillows. When our flights got cancelled they were super quick to respond on whether we could extend. The rooftop access is unparalleled and provide a view over all of Copenhagen in addition to beautiful place to have a glass of wine. The only drawback as noted by others is the night club noise, which was only really loud on Friday & Saturday. We just closed the windows when we went to sleep and it was fine.
