Martin’s place was a wonderful part of our stay in Berlin. The apartment itself was cozy, extremely clean, centric, and less than a 1 minute walk towards the metro. It had everything you could need. In terms of Martin himself, the dude’s a class act. Our communication was great and he even stayed with us for a while to give us his recommendations (listen to what he says, he knows his stuff), and tips. Would definitely stay there again. Don’t think about it, book this apartment.
