Aden Immobilien on Grünberger Strasse provided me with invaluable assistance in preparing, facilitating and completing the sale of my Berlin apartment from abroad, while I was living in France. Excellent support, both practical and administrative, with real multilingual skills and efficient relational networks. The valuation of the property for sale was also done in an optimal way, allowing a good sale price without negotiation. For these reasons, I recommend this agency (and I thank its French consultant, Olivier Montero).
