My husband and I stayed for two weeks in Denise's apartment. We didn't get a chance to meet her in person, but communication was great! She even arranged for a friend to meet us when we arrived which was extremely nice and helpful. The apartment is cozy with a well equipped kitchen and a great view of the TV tower. It's perfectly situated a couple minutes from Alexanderplatz and an easy 30 min walk or 10-15 train ride to most other sites (like the East Side Gallery and Brandenburg Gate). The building is on a very quite street with a nice balcony and restaurants and a grocery store directly across the street. We would definitely recommend staying here!!
