Albertin Hotel 

The hotel is exceptionally clean and tidy, there were no cosmetic issues in any of the rooms I was in whatsoever. The staff were friendly and helpful and the hotel itself is very quiet. We had a triple room which was very spacious with a really nice bathroom which was very clean and tidy as well. The beds were comfortable and there was no noise in the hotel at night at all. We stayed for 2 nights for a city break in Berlin, the tram stops right outside the hotel, and it is about a 20 minute journey to the centre of Berlin. Don't let the distance put you off the journey is a nice one passing through many different sites along the way and it is only 5 euros for a whole day travel (this also includes the tube and buses). The hotel offered a breakfast in the mornings from 8-10pm, it was simple nothing fancy but it was definitely enjoyable. The hotel was amazingly cheap as well, I'd definitely recommend coming here for a city break.
