Celine was one of the best hosts that you could ever ask for. She was incredibly helpful in recommending restaurants and sights to see in Berlin! Her apartment is very close to both Berlin HBF and Alexanderplatz. So taking the S-Bahn could not have been any easier. Her apartment is also very close to many sights like the Berlin Wall memorial, Tiergarten, and Museum Island. Would definitely recommend and would definitely stay here again!
