Martina's flat is very centrally located in the Hip Mitte area with access to lots of different restaurants, cafes, bars and shops.
The weather was lovely so we managed to get around to the sights around Alexander platz, museums, etc on foot. Not more than 30 mins to historical parts.
The flat is large with 2 comfortable bed rooms with a living room and attached kitchenette.
Martina was very communicative and helpful. Would definitely recommend staying at her flat.
