Heliodor is a fantastic apartment. Bright, spacious, very comfortable & well provisioned with everything you need for a great stay in Berlin. It is set in a fantastic location very close (a minute or 2 walk) from Magdalenestrasse U bahn station making it easy to get to from airports & a great place from which to explore the city. It is also very handy for shopping (Lidl & local shops) & a couple of very reasonably priced restaurants. We loved our stay & would recommend this apartment to anyone visiting Berlin.
