Overall experience was awesome:
Very clean, big, light room with all facilities, bed is very comfortable,room have space to work, bath/toilet and kitchen is very clean and accessible, location is good- just few steps to metro.
Mr.Muhammed is the best host ever, very gentle and positive guy and offered me complimentary welcome snacks, tea/juice/water and national super tasty dinner.
Definitely recommended place to stay in Berlin.100% above expectations.
