My friend and I were so pleased with our accommodations at Heliodor Apartments. The flat where we stayed was very modern, with a very nice kitchen and bathroom. It was clean and spacious. I loved the upstairs loft, which was where slept, and my friend slept in this amazing sleigh bed. The apartment was just steps away from the undergound train, going to Alexanderplatz. I highly recommend Heliodor Apartments. One last note, the host is GREAT!! Thank you, Michael.
