Certain factors such as the location and condition, an appropriate layout, as well as the size and features can increase the value of a Berlin property tremendously. For example, two-bedroom apartments with 100 square meters of living space are hardly ever sought. The optimal apartment has, according to a recent study from a large German property portal, an average of 66 square meters and 2.5 rooms.In Berlin the situation for condominiums is crucial. If the apartment is in a trendy neighbourhood or near a specific location, the price can be much higher than the next block just around the corner. Similarly, the close connection to public transport plays a major role as well as the orientation of the apartment and its location within a multi-family house.
