The location of the apartment is in a very safe and convenient part of Berlin with many cafes to eat at and stores to go shopping. The U-bahn, S-bahn, trams & buses are all within walking distance to get on. Check-in was easy & quick. Ellen and her assistant Christina were very prompt in answering any questions or concerns about the apartment . Apartment was very clean & stylish and I would definitely stay here again for any future visits to Berlin!
