I've stayed at that Adina Aparthotel. I found the hotel to be extremely convenient for location and amenities. I booked a one-bedroom in order to be assured of having a washer and dryer. I requested a courtyard unit at checkin, which was very quiet. The hotel is a 10-minute walk or one tram stop away from the Hauptbahnhof, which is a transportation hub for Berlin. One stop in the opposite direction is a shopping street with a convenient supermarket for snacks, drinks, etc. The only issue I had was with the internet, but my stay was several years ago and I imagine the problem is now solved. The breakfast was very good at the Adina. I've found that chain to be very reliable in Germany and really liked the Nuremberg location.
