Karolina & Philipp's flat is very centrally located in Berlin Mitte, five minute's walk to a nearest metro station. It's in a quiet street and neighbourhood, yet you find all services, including a supermarket and several eateries and cafés nearby.
The flat is ideal for an extended city break. All four beds are comfortable. Kitchen is well equipped. Note that there is no A/C, but a portable fan is provided. We did not need it in hot June days, though.
Check-in was easy, everything worked as expected. Karolina and Philipp even provided welcome drinks (water and Berliner beer).
We recommend the place.
