Martin, was a great host. He gave me a quick tour of the apartment. He had recommendations and was available.
The apartment itself was very clean, good Wi-Fi and a very comfortable bed, just as photos appeared on Airbnb. It had a small but practical kitchen which I used as I was there about a week.
The apartment is divided into two sections. You enter a small hall- to the left is a kitchen with a loft bed above and on the right side is a living area and small dining table with another loft bed.
The closest U-Bahn/S-Bahn is about a 10-15 minute walk but right outside the apartment you can pick up bus M41 which I used every day and It gets you everywhere quickly which I used every day.
Highly recommend!
