Nassa's apartment was perfect for our stay in Berlin! It really is a gorgeous place, and looks exactly like the pictures. The location CANNOT be beat, as it's a 5 minute walk to a train station that takes you to all of the main tourist areas. The neighbourhood itself is really cool as well, and we spent most of our evenings in Berlin just exploring the area around the apartment. Nassa was also excellent to communicate with, and check-in was a breeze. We were over an hour late for the time we agreed to meet because of missed trains, and without a working cell phone we couldn't contact him to let him know, but he was totally understanding and welcoming anyway. I would definitely stay here again!
