Andrew apartment is ideal for short or long stay in Berlin. I got it clean, is very well equipped, I had no problem with the internet connection, it worked very well throughout the week I was there. The location is perfect, steps from the subway station Nollendorfplatz communicating with all the sights of Berlin. You can also walk to the downtown area of west side. If you want to enjoy the atmosphere and bars of Schöneberg is the best location too.
Andrew was very friendly and helpful throughout my stay. I would definitely choose this apartment again.
