We stayed 4 days in the flat. Excellent location, easy transport from the airport by train and only 10 minutes walk from the nearest train station in Berlin. Very easy and convenient to walk to most of the tourist sights in Berlin. The flat was spacious, clean, really clean bathroom and good size, warm, comfortable. Lovely quiet neighbourhood with plenty of restaurants nearby. Maria was very quick to respond to any questions, we had. Would happily stay in this flat again and can thoroughly recommend this flat to anyone wanting to stay in Berlin.
