The apartments are super clean, modern and a 20 minute walk from the centre. The furniture and beds are very comfortable and cosy, the balcony has a great dining space. Opposite the building is the Nordbahnhof train station, which is very busy, you can hear the trams and trains when it is quiet in the apartment, however we still slept well! It's a great location to explore the city and we had a great time. :)
