Great accommodation just like in the pictures. We arrived a bit earlier and were able to check-in beforehand. Our trip was in December so outside was quite cold but it was very warm and cozy in the apartment. The staff were very friendly and helpful. We were a little lost where to go when checking in, but communication was always quick. Location is also great with several public transport stations and not a far walk to Alexanderplatz. Would definitely visit Nena Apartments again and totally worth the recommendation!
