Annika's place is a perfect place to stay in Berlin. The flat has a very convenient location: public transport, a direct bus to Tegel, Tiergarten, some nice bars are flowing around the place. The flat itself is professionally taken care of, clean, cosy with a very nice balcony and view. I've experienced some difficulties with my luggage upon arrival at Berlin's Tegel, both Annika and Johannes were very understanding and helpful, providing me with some essentials, clothes and a welcoming complimentary Sekt. 100 % recommended.
