I could not recommend this apartment enough! Baerbel was so accommodating and lovely. The apartment itself is a great size, so clean and has a great balcony overlooking the street - perfect to sit out with a beer and watch the street life. The kitchen and bathroom are both great!
The apartment is only a short stroll to the subway/train which takes you right into the city centre. There is a great supermarket only a few minutes walk and heaps of cheap restaurants/cafes in close proximity! No longer how long you plan to spend in Berlin, this place is absolutely ideal.
