Nice and stylish appartment in the middle of Berlin in walking distance to tourist hotspots like "Museumsinsel" and "Berliner Dom". The appartment is smaller than it appears in the pictures but besides that everything is as depicted.
Check-in and communication was super easy.
Unfortunately it was a very hot week and there's no aircondition in the appartment which made especially sleeping at night a challenge. So in the summer I wouldn't recommend it. But any other time it's definitely recommended.
