Cosy penthouse with a private Loggia

We are a French couple of 32 and 35 years old. We have been living in our beautiful and cozy penthouse since January 2025, but are looking for a cheaper flat within the ring, around Kreuzberg :) Our current flat is situated on the last floor and has a direct access to a 40m2 rooftop with a private loggia, where you can enjoy barbecues in summer. The building is an Altbau, offering beautiful features on the common areas. The neighborhood is very calm, all grocery stores closed by.
