We stayed in the Alexandra apartment which really nice, even worth climbing the four flights of stairs as there is no lift! It was spacious, clean and very functional. The beds were so comfortable and everywhere is tastefully decorated. The location is great, very central right next to the round tower and handy for the metro so getting around was very easy. the communication and service was top draw so I would throughly recommend the Rosenberg apartments and will look forward to staying there again on my next trip to Copenhagen!
