The apartment is spacious and well located with a tram right outside the building. This made getting around the district and the city very easy.
As others reviews have pointed out, Marc uses an agent to manage the property and this complicated the check-in process. When we arrived at the apartment, we were informed by the agent that we needed to pay the Berlin City Tax in cash (55 Euro). This was not outlined in Marc's Airbnb advertisement, and exchanging money outside of the Airbnb website is not part of the company's policy (and is actively discouraged).
