Hotel was great for what we needed it. Room very clean and bar/reception always had someone there. We arrived midnight and there was someone there to give us our key.
Although it looks close on a map, the hotel is about a 40 minute walk away the Mitte and also 30/40 minutes from Kreuzberg. However there is an Underground train 5 mins away.
Overall, very satisfied with the hotel and would recommend it to anyone wanting to visit Berlin!
