We loved staying at Stamatis place. Communication with Stamatis was easy from the first contact. The apartment is even larger and more comfortable than the photos indicate. The location is terrific, very close to the trams at Zionskirche plaza and the UBahn at Rosenthaler place , surrounded by great restaurants and coffee shops, and in the middle of a lively neighborhood. It's easy to walk or take public transport to the main sights of Berlin. Wifi is good and because the apartment faces on to an enclosed courtyard it is quiet. There are convenience stores close by and a supermarket two blocks away. The added bonus , especially when it is hot, is the homemade Eis (ice cream) stand at the entrance to the apartment block.
