Amazing appartement, great location and most important: great host.
We are family with 3 big children, had 1 week vacation in Berlin at Frank's place.
Our vacation was great thanks to Frank.
Most of the week was very cold (arround 3 deg), and it was great to come back to a lovely warm place every day.
The appartement equipped with every thing that you can dream on. We even stayed 1 full day at the appartement because it was too cold outside and watched Netflix all day and looked at the falling snow outside.
Frank left us a manual that explain how to use the equipment in the appartement + useful tips on places in Berlin.
Highly recommended.
