I stayed atOtto Hotel a few years ago and I talked several times of the hotel because it seemed beautiful to me. Although not entirely low cost, I had paid little for it because I had taken it inside one super offer, in short, it is a 4 star in all respects. Perfect.
What surprised me, besides the huge room, was the breakfast. The top floor of the structure, which is located at Charlottenburg is dedicated to breakfast. The place is beautiful because the room has aentire glass wall overlooking the rooftops of Berlin. In summer it is also allowed to have breakfast on the terrace, in winter it is not recommended: S.
Breakfast is completely organic, you should hear the yogurt or cereals, Or herbal teas. I had a sweet and savory breakfast every day, just so I didn't miss anything, but also because it was really delicious and the degrees outside the hotel were below zero. It was mandatory eat a lot :D
Breakfast is arranged on an island in the middle of the room and all around tables for two and four seats with a different flower per table every day, really nice. On the last morning, as my plane left early, I had breakfast with dawn outside. Really beautiful, the place and the location. Advised.
