We recently spent 2 weeks in Frank's Berlin apartment. We found it to be very comfortable and cosy. The apartment was as described and even better. All our emails were answered by Frank very quickly. Check-in and out was super easy. The location was very good for us and liked that it is in a residential area with cafes and shops a short walk away. The kitchen is modern and fully equipped. Also, 3 different coffee making options! We would recommend Frank's apartment and would definitely stay again.
