Frank’s place is conveniently located in the central Mitte district, a comfortable walking distance to main attractions like Museum Island. If walking is not your thing, there are trams and bahns nearby that can connect you to anywhere in Berlin. I was staying alone, so Frank’s cosy apartment was comfortable for me. Pro tip: If you plan to lock the front door, remember to unlock it before you actually open the door, or the latch gets stuck. Somehow this happened to me twice during my trip.
