Markus has been exceptional from the day I requested for the booking. The day we were supposed to arrive, we were pretty late and reached past midnight and to our surprise Markus was up till the time we all got set in our room. The apartment was really spacious, clean and in a very nice location pretty close to the city centre. If I plan on being back to Berlin next time, I would definitely try to book over this one again. And trust me there is nothing that would disappoint you with Markus' place.
