We stayed 4 nights at Alex's and it was fantastic. The location is incredible, you can go across the street and enjoy the park by the river or you can walk to downtown in 15 minutes! We went 3 times to Nyhavn, it just takes around 20 minutes! The communication with Alex was flawless and he answered all our questions (and more) in minutes. Plus, he gave us a whole bunch of thinks to do around Copenhagen... Thanks Alex!
