A central location in Berlin that is good for first time explorers of the city. It's roughly a 20 minute walk to major attractions like the Reichstag, Brandenburg Gate, Checkpoint Charlie, Topography of Terror, the remains of the Berlin Wall, etc. It's about a 10 minute walk to the metro station.
The apartment itself is modest, but plenty large and very quiet at night. It is tucked away well off the street, so there's not a sound at night.
Even though the flat is within walking distance of major attractions, the immediate neighborhood is not super trendy or exciting. It's definitely not a vibrant area lined with cafes and bars and restaurants - although you could walk about 1km to find a few.
Overall this is a good place to stay for seeing major attractions in the city - especially if you want to peace and quiet at night.
