This place is very conveniently located 800m north of Ostbahnhof train station. Holzmarkt with nice outdoor bars is around 20min walk. The immediate surroundings of this area are a bit rough still, places under construction and graffiti. But that is quite common in Berlin it seems. I was here for a busy three days startup event, so was out most of the time. But the apartment was very clean, spacious and has a modern interior. Bathroom good and clean, shower head a bit too low for me. Bed is ok, it’s a sleeping-coach. If you come as a couple you might find it a bit small and hard. But all in all great value for the price. And Marius is a nice guy, easy to communicate with. I would definitely stay again.
