I stayed one month in Lorettas apartment. I must say that the location and the flat are great. I had one moth German course in Freie Universtität Berlin. From Nollendorplatz U-Bahn it was easy to reach. U-Bahn Nollendorfpaltz is only 100 meters from the flat. From there you can find U1,U2,U3 and U4. So very easy to reach whole Berlin!
Schöneberg is great area to live. It is full with restaurants and life. KaDeWe is only one U-bahn stop away and in Nollendorfpalz is a big food shop.
Flat is really nice and quiet! Top floor with balcony. I will definitely go back here. Loretta Helped with everything and was very nice host!
