However, do note that the downside to it was the long duration spent in the bus.
The journey is around 9 hours, with 1 or 2 stops along the way.
I find it okay as the seats was comfortable and spacious too.
P.s. Please have some form of entertainment/ snacks for your journey.
 By the time we reached Berlin, it was already around 7pm in the evening.
We slowly made our way to the hostel that we booked- Cityhostel Berlin.
It is located near to Mohrenstraße Underground railway station.
Approximately a 3 min walk away from it.
It cost: $205.00 SGD (3 nights) 
Quadruple Bunk beds with shared bathroom.
Booked through (Agoda), photo credits from the website.
 Loving how the reception is being decorated.
Do note that since this hostel is really huge and there are many rooms, it may be a noisy at times.
Also, the toilets do not have proper doors for bathing but only have curtains.
However, staffs were friendly and helpful.

Had a quick dinner nearby the hostel at a vietnamese place before calling it a day.
