Nena Apartments Metropolpark Berlin was a very nice place to stay at. The appartement was very close to the metrostation and there was 24/7 security so you could even get in at 4 am. The rooms were very nice and clean and the staff was very helpful.
However if you’d like to party this is not the place for you. You have to be considerate to the residents that live upstairs and thats why outside of your room you have to talk with a whisper. Inside of your room you cant be too loud either. The room itself was very hot and warm, it would have been nice if there was airconditioning of some kind.
