We had a lovely stay in Alex's apartment! We stayed in 3 different apartments during our Berlin Visit (to experience 3 different vibes of Berlin), and in the end we wished we'd stayed in his the whole time! It felt warm and homey while still feeling clean and modern. Alex was flexible with check-in and check-out and was so communicative throughout the whole process. We'd definitely stay again next time we're in Berlin and would recommend staying here to anyone. It was the perfect size for a couple.
