The overall state was nice, the suite comfortable but the room service cleaning not sufficient. First day, they didn't restock the cosmetics and toilet paper roll, the next day not only that, but also the soap dispensers, the cups were just wiped or rinsed, not cleaned - lip stains remained, tea and coffee weren't restocked...the receptionist were friendly and hilfsbereit but the cleaning staff probably needs retraining or to care more. Overall, clean and modern hotel.
Good public transport connection, position at Anhalter Bahnhof - 2 stops from Potsdamer Platz even though the name suggests position directly there.
