Hae-Ok is a wonderful host. Very easy to communicate with before and during the arrival. She met us at the apartment and gave us several tips. The apartment is very well located, a few steps from Alexander Platz and Berliner Fernsehturm (with a beautiful view to the tower) . Is also very large, have a very well equipped kitchen and a very clean bathroom. The only problem is the couch. It's old and doesn't smell good. We had to put a sheet over it to sit. Talking about sheets, the sheet of one of the beds from the smaller room had stains on it. Even though these little problems, I would recommend this place.
